# Specify the storage used by Krill.

|

# Currently, Krill supports disk based storage only.
|

#
|
|
# You can use a shared disk and a standby Krill node for redundancy.
|
|
# However, data corruption issues can occur if you run multiple active
|
|
# Krill nodes using a shared disk. Therefore, you MUST ensure that only
|
|
# one Krill node is active at any given time.
|
|
#
|
|
# Example configurations:
|
|
# storage_uri = "/var/lib/krill/data/"
|
|
#
|
|
# Default:
|
|
# storage_uri = "./data"

# If you want to support remote delegated CAs to be children under a CA

# Specify the HTTPS mode. Krill supports three modes:

# "generate" (DEFAULT)
|
|
#
|
|
# Krill will generate a key pair and create a self-signed certificate
|
|
# if no previous key pair or certificate is found. File names used
|
|
# are data_dir/ssl/key.pem and data_dir/ssl/cert.pem respectively.
|
|
#
|
|
# "existing"
|
|
#
|
|
# Krill expects an existing key pair and certificate in the same
|
|
# locations where it would otherwise store its generated key pair
|
|
# and self-signed certificate.
|
|
#
|
|
# "disable"
|
|
#
|
|
# Krill will use plain HTTP.
|
|
#
|
|
# This mode is not recommended as HTTPS adds little overhead, and
|
|
# even with a self-signed certificate provides better security
|
|
# out of the box.
|
|
#
|
|
# That said, if you are running an HTTPS proxy server on the same
|
|
# host as Krill and Krill is listening on localhost only, then
|
|
# using plain HTTP between Krill and your proxy server may be an
|
|
# option you would want to use.
|
|
#
|
|
# We recommend STRONGLY that you do not use this option if your
|
|
# Krill instance is configured to bind to a public IP address.
|
|
#
|
|
# **NOTE**: Even if you use "disable" here, Krill still insists on
|
|
# using HTTPS for its service_uri. See below.

|
#
|
|
### https_mode = "generate"
|
|
|
|
# Specify the base public service URI hostname and port.
|
|
#
|
|
# The default service URI is set to https://localhost:3000/. This is fine
|
|
# for setups where you use Krill to run your own CA only. You do not need to
|
|
# set this to enable remote access to the UI or API (e.g. for using the CLI
|
|
# remotely). Simply setting up a proxy suffices for this.
|
|
#
|
|
# However, if you are serving as a parent CA or Publication Server that
|
|
# needs to be accessible by remote CAs, then you will need to tell your
|
|
# Krill instance what its public (base) URI will be, so that it can include
|
|
# the proper URIs in responses to those CAs.
|
|
#
|
|
# Note that Krill insists on HTTPS for this, even if you elect to use
|
|
# "disable" for the https_mode. The reason is that, while RFC 6492
|
|
# (provisioning) and RFC 8181 (publication) allow for plain HTTP and provide
|
|
# security through signed messages, we believe it is better if this (remote)
|
|
# traffic is also encrypted and one can (and should) use an HTTPS capable
|
|
# proxy in this case.
|
|
#
|
|
# At present this MUST be an https URI with a hostname and optional port

# number only. It is not allowed to use a Krill specific path prefix. If you

|
# ROA Aggregation
|
|
#
|
|
# It is recommended that separate ROAs are used for each authorized prefix,
|
|
# even though the RFC allows for multiple prefixes for the same ASN to be
|
|
# combined on a single ROA object. The reason for this is that the ROA will
|
|
# become invalid if any of the listed prefixes no longer appears on your
|
|
# CA's certificate. Note that Krill will automatically clean up
|
|
# over-claiming ROAs when it finds that its resources have been shrunk, but
|
|
# there is a possible time window where ROAs can be invalid before Krill
|
|
# discovers the shrinkage.
|
|
#
|
|
# That said, if there would be too many ROAs then this will impact all RPKI
|
|
# validators, therefore Krill will by default start aggregating ROAs per ASN
|
|
# when more than 100 ROAs would be issued. Conversely, Krill will start de-
|
|
# aggregating again when the number of authorizations drops below 90.
|
|
#
|
|
# This behaviour can be overridden with the following directives:
|
|
# roa_aggregate_threshold = 100
|
|
# roa_deaggregate_threshold = 90
|
|
|
|
|
|
#
|
|
# Republication Intervals
|
|
#
|
|
# The RPKI uses Manifests (RFC 6486) to communicate the list of current RPKI
|
|
# objects (such as ROAs) to RPKI Validators. Manifests are used to protect
|
|
# against attacks, or incidents, where Validators only see a partial view of
|
|
# the RPKI repository. For this to work properly Validators will need to
|
|
# know how 'fresh' the Manifests are - otherwise they would be vulnerable to
|
|
# replay attacks where they are presented old versions of Manifests thus
|
|
# withholding them from discovering new RPKI objects.
|
|
#
|
|
# Krill issues manifests with a default next update and validity period of
|
|
# 24 hours, plus a random value between 0 and 4 hours. This random value is
|
|
# added in order to spread out scheduled next publication times between CAs.
|
|
#
|
|
# This means that the maximum replay window is 28 hours. Krill checks every
|
|
# 10 minutes whether the next update time is less then 8 hours (by default)
|
|
# in the future, and in that case it will re-issue them to avoid that
|
|
# Validators would end up with expired manifests. This means that an
|
|
# operator has a minimum of just under 8 hours to deal with issues with
|
|
# their CA or Publication Server before RPKI Validators would notice.
|
|
#
|
|
# The default values can be overridden, but with care.. make the next update
|
|
# interval too short and this causes too much work for all RPKI validators,
|
|
# puts load on your publication server and shortens your window to deal with
|
|
# issues. Make it too long and you could be vulnerable to replay attacks.
|
|
# Re-issue to quickly and again you cause extra load to RPKI validators and
|
|
# publication server.
|
|
#
|
|
# All that said.. if you are willing to accept the, in practice, small risk
|
|
# of a replay attack then you could for example opt for a
|
|
# 'timing_publish_next_hours' value of 48 hours, and a
|
|
# 'timing_publish_hours_before_next' value of 24 hours. That way you would
|
|
# have a full day to fix issues.
|
|
#
|
|
# timing_publish_next_hours = 24 # (must be 2 or higher)
|
|
# timing_publish_next_jitter_hours = 4 # must be 0 - timing_publish_next_hours / 2

# timing_publish_hours_before_next = 8 # (must be 1 or higher)
|
|
|
|
|
|
#
|
|
# ROA and Delegate Certificate Times
|
|
#
|
|
# Krill will issue ROAs, and child CA certificates if you have delegated
|
|
# resources to child CAs, with a "not after" time of 52 weeks from issuance,
|
|
# and it will re-issue those ROAs and certificates 4 weeks before they would

#
|
|
# Custom authorization policies are intended to handle requirements that are too
|
|
# complex for just the settings available in krill.conf and is an advanced
|
|
# topic beyond the scope of this documentation.
|
|
#
|
|
# The built-in policies treat the following user attributes specially:
|
|
#
|
|
# - "role" - One of "admin", "readwrite" or "readonly". See the full Krill
|
|
# documentation for more information about which permissions are
|
|
# associated with each role.
|
|
# - "inc_cas" - A comma-separated set of CA handles which should be included
|
|
# in the set the user is permitted to see. If present this
|
|
# attribute will prevent the user seeing or interacting with any
|
|
# CA handle that is not in this set.
|
|
# - "exc_cas" - A comma-separated set of CA handles which should be excluded
|
|
# from the set the user is permitted to see. Overrides inc_cas.
|
|
# If inc_cas is not set, any CA handle NOT in exc_cas will be
|
|
# visible to the user who may interact with it according to
|
|
# the permissions granted to the user (e.g. through a role
|
|
# assignment).
|
|
#
|
|
# Note: The inc_cas and exc_cas settings only restrict visibility of and
|
|
# interaction with specified CAs via the Krill web UI. CA handles are still
|
|
# visible in the repository content and metrics output by Krill.

|
# the URL of the OpenID Connect provider discovery
|
|
# endpoint. "/.well-known/openid_configuration"
|
|
# will be appended if not present. Krill will fetch

# this URL does not match the "issuer" value in the

|
# discovery endpoint response or if the discovery
|
|
# endpoint cannot be contacted, Krill will fail to
|
|
# start.
|
|
#
|
|
# client_id Yes Provided by your OpenID Connect provider.
|
|
#
|
|
# client_secret Yes Provided by your OpenID Connect provider.
|
|
#
|
|
# insecure No Defaults to false. Setting this to true will
|
|
# disable verification of the signature of the
|
|
# OpenID Connect provider token ID endpoint
|
|
# response. Setting this to false may allow attackers
|
|
# to modify responses from the provider without
|
|
# being detected. Setting this to false is strongly
|
|
# discouraged.
|
|
#
|
|
# extra_login_scopes No Provider specific. Defaults to "". A
|
|
# comma-separated list of OAuth 2.0 scopes to be
|
|
# passed to the provider when a user is directed to
|
|
# login with the provider. Scopes are typically
|
|
# used to instruct the provider to send additional
|
|
# user details along with provider token responses.
|
|
# One common scope is "profile" which often causes
|
|
# the server to respond with email addresses and
|
|
# other personal details about the user. If the
|
|
# OpenID Connect provider discovery endpoint shows
|
|
# that "email" is a supported scope then the "email"
|
|
# scope will be requested automatically, you don't
|
|
# need to specify it here in that case.
|
|
#
|
|
# extra_login_params No A { key=value, ... } map of additional HTTP query
|
|
# parameters to send with the authorization request
|
|
# to the provider when redirecting the user to the
|
|
# OpenID Connect provider login form. Section
|
|
# 3.1.2.1. Authentication Request in the OpenID
|
|
# Connect Core 1.0 specification [*2] lists various
|
|
# parameters that can be sent but the supported set
|
|
# varies by provider. The prompt=login parameter is
|
|
# automatically sent by the provider (though this
|
|
# behavior can be disabled, see prompt_for_login
|
|
# below) and thus does not need to be provided
|
|
# using this setting. Can also be specified as a
|
|
# separate TOML table, e.g.:
|
|
#
|
|
# [openid_connect.extra_login_params]
|
|
# display=popup
|
|
# ui_locales="fr-CA fr en"
|
|
#
|
|
# prompt_for_login No Defaults to true. Setting this to false will
|
|
# disable the default behaviour of sending the
|
|
# prompt=login parameter to the provider. This
|
|
# also allows a different prompt=<value> to be
|
|
# specified using extra_login_params, from the set
|
|
# defined in Section 3.1.2.1. Authentication
|
|
# Request in the OpenID Connect Core 1.0
|
|
# specification [*2]: "none", "login", "consent"
|
|
# or "select_account".
|
|
#
|
|
# logout_url No A URL to direct the browser to redirect the user
|
|
# to in order to logout. Ideally this is not needed
|
|
# as the provider OpenID Connect Discovery response
|
|
# should contain the details Krill needs, but for
|
|
# some providers a logout_url must be specified
|
|
# explicitly. If the provider discovery response
|
|
# doesn't announce support for any supported
|
|
# mechanisms and no logout_url value is set then
|
|
# Krill will default to directing the user back to
|
|
# the Krill UI index page from where the user will
|
|
# be directed to login again via the OpenID Connect
|
|
# provider.
|
|
#
|
|
# claims No A { <claim>={...}, ... } map used to extract and
|
|
# +-- source No optionally transform claim values from the OpenID
|
|
# +-- jmespath Yes Connect provider responses [*3, *4]. Each claim
|
|
# +-- dest No specification results in zero or one additional
|
|
# attribute name=value pairs that can be shown
|
|
# in the Krill web UI and can be tested by the
|
|
# authorization policy.. Can also be specified as
|
|
# a separate TOML table, e.g.:
|
|
#
|
|
# [openid_connect.claims]
|
|
# name = { source="...", jmespath="...", dest="..."}
|
|
# name2 = { ... }
|
|
#
|
|
# An "id" claim is required. If not specified the
|
|
# following default "id" claim configuration will
|
|
# be used:
|
|
#
|
|
# id = { jmespath="email" }
|
|
#
|
|
# To prevent attributes being sent to the UI, use
|
|
# the auth_private_attributes setting (see above).
|
|
#
|
|
# source If the 'source' subfield is not provided, all
|
|
# available token and userinfo claim responses from
|
|
# the OpenID Connect provider will be searched for
|
|
# a field that matches the 'jmespath' expression.
|
|
#
|
|
# If specified the value identifies a specific
|
|
# claim set to search and can be one of the
|
|
# following values:
|
|
#
|
|
# config-file
|
|
# id-token-standard-claim
|
|
# id-token-additional-claim
|
|
# user-info-standard-claim
|
|
# user-info-additional-claim
|
|
#
|
|
# The source = "config-file" value is special, it
|
|
# doesn't refer to an OpenID Connect provider
|
|
# response claim set but rather to user attributes
|
|
# looked up using the "id" claim value as a key to
|
|
# index into the [auth_users] user attribute map.
|
|
#
|
|
# The "id" claim value cannot therefore itself be
|
|
# taken from [auth_users], and password_hash values
|
|
# in [auth_users] are ignored as authentication is
|
|
# handled by the OpenID Connect provider.
|
|
#
|
|
# dest The optional "dest" field can be used to set the
|
|
# value of an attribute by a different name than
|
|
# the claims key used. This can be used to specify
|
|
# multiple claim rules that attempt to extract a
|
|
# a value for the same claim. The first matching
|
|
# rule in such cases will be used.
|
|
#
|
|
# jmespath The "jmespath" field specifies a JMESPath [*5]
|
|
# expression which is used to find a matching field
|
|
# in the OpenID Connect provider JSON response. In
|
|
# addition to the standard JMESPath functions the
|
|
# Krill implementation includes two custom regular
|
|
# expression based functions to match and
|
|
# optionally replace parts of the value of the
|
|
# fieldm matched by the JMESPath expression. These
|
|
# two functions are:
|
|
#
|
|
# recap(<field name/value>, 'capturing regex')
|
|
# resub(<field name/value>, 'search regex', replace'))
|
|
#
|
|
# With these extra functions cases where part of a
|
|
# complex string should be matched, extacted and
|
|
# (with resub) mapped to a value that matches what
|
|
# the authorization policy expects. E.g. it could
|
|
# be used to match a substring and then to "output"
|
|
# a particular Krill role name.
|
|
#
|
|
# If the combination of "resub()" and "dest" is
|
|
# not powerful enough you can take value matching
|
|
# even further using policy file rules. "dest" and
|
|
# "resub" may be combined with policy file rules in
|
|
# order to simplify the policy file rules needed.
|
|
#
|
|
# When determining the right "jmespath" expression
|
|
# to use, match failures will be logged at "info"
|
|
# level (as the auth policy in use may not require
|
|
# all configured claims to be found for all users)
|
|
# including a list of claims that are available to
|
|
# match. Additionally at "debug" level details
|
|
# about the claim search process are logged and at
|
|
# "trace" level the OpenID HTTP Connect provider
|
|
# HTTP/JSON responses are logged.
|
|
#
|
|
# Escaping: If you need to use double quotes to
|
|
# escape a JMESPath identifier you will need to use
|
|
# jmespath='...' or jmespath='''...''' instead of
|
|
# jmespath="..." in the Krill configuration file.
|
|
# See the JMESPath [*6] and TOML [*7] specs for
|
|
# more information about quoting and escaping.

# Registering Krill with an OpenID Connect provider:
|
|
# ------------------------------------------------------------------------------
|
|
# In order to communicate with an OpenID Connect provider, Krill must first be
|
|
# registered with that provider. As a result of registration you will be issued
|
|
# a client_id and a client_secret, and possibly also an issuer_url (or you may
|
|
# have to consult the provider documentation to determine the issuer_url).
|
|
#
|
|
# When registering you will usually need to specify a callback URL. For Krill
|
|
# this should be <service_uri>auth/callback (replace <service_uri> with the
|
|
# actual value set above).
|
|
#
|
|
# When auth_type = "openid-connect" the client details MUST be provided to Krill
|
|
# via settings in the [auth_openidconnect] section of the configuration file.
|
|
#
|
|
# ------------------------------------------------------------------------------
|
|
# Required OpenID Connect provider capabilities:
|
|
# ------------------------------------------------------------------------------
|
|
#
|
|
# The OpenID Connect provider must implement the following specifications:
|
|
#
|
|
# https://openid.net/specs/openid-connect-core-1_0.html
|
|
# https://openid.net/specs/openid-connect-discovery-1_0.html
|
|
# https://openid.net/specs/openid-connect-rpinitiated-1_0.html
|
|
#
|
|
# At the issuer_url endpoint the provider MUST announce support for at least the
|
|
# following:
|
|
#
|
|
# "issuer": ".."
|
|
# "authorization_endpoint": "..",
|
|
# "token_endpoint": "..", ("userinfo_endpoint" is also supported if available)
|
|
# "jkws_uri": "..",
|
|
# "scopes_supported": ["openid"]
|
|
# "response_types_supported": ["code"]
|
|
# "response_modes_supported": ["query"]
|
|
# "grant_types_supported": ["authorization_code"]
|
|
# "id_token_signing_alg_values_supported": ["RS256"]
|
|
# one of: "end_session_endpoint": ".." or "revocation_endpoint": ".."
|
|
#
|
|
# ------------------------------------------------------------------------------
|
|
# A note about HTTPS certificates:
|
|
# ------------------------------------------------------------------------------
|
|
# If the provider URLS are HTTPS URLs (which they should be unless this
|
|
# deployment of Krill is only for testing) then the HTTPS certificate must have
|
|
# been issued by a CA in the O/S CA certificate store, i.e. either a well known
|
|
# authority that is included in the store by default, or a custom CA that you
|
|
# have added to the store yourself. Krill will fail to connect to a provider
|
|
# that uses a self-signed certificate or a certificate from an unknown root
|
|
# certificate authority. For more information see for example:
|
|
# http://manpages.ubuntu.com/manpages/xenial/man8/update-ca-certificates.8.html

# A note about end_session_endpoint and revocation_endpoint:
|
|
# ------------------------------------------------------------------------------
|
|
# "end_session_endpoint" is defined by various [*1] OpenID Connect draft
|
|
# specifications relating to logout. In Krill it is used for the purpose defined
|
|
# in the OpenID Connect RP-Initiated Logout 1.0 spec [*1], namely for Krill as
|
|
# the RP (OpenID Connect terms Krill a Relying Party in this context, which is
|
|
# particularly confusing given that the term Relying Party also has meaning in
|
|
# Krill's native RPKI domain) to be able to initiate logout of the user at the
|
|
# provider. Krill also requires that the endpoint either honours the
|
|
# "post_logout_redirect_uri" HTTP query parameter (defined as OPTIONAL in the
|
|
# spec) or that the provider can be configured with corresponding behaviour,
|
|
# i.e. to redirect the end-user user-agent (browser) back to Krill after logout
|
|
# is completed at the provider. If support for this is lacking it is undefined
|
|
# where the user will end up after logout, which is not an issue if the user
|
|
# was finished with Krill, but is annoying if the logout was done in order to
|
|
# re-login to Krill as a different user. At least one provider has been observed
|
|
# which does NOT support this endpoint.
|
|
#
|
|
# As an alternative Krill also supports "revocation_endpoint"
|
|
# (see https://tools.ietf.org/html/rfc7009 "OAuth 2.0 Token Revocation") which
|
|
# is used to terminate the users login session at the provider without leaving
|
|
# the Krill web UI.
|
|
#
|
|
# Finally if neither of these mechanisms are supported a logout_url can be
|
|
# specified explicitly via configuration.

# This example is for a local test deployment of RedHat KeyCloak:
|
|
#
|
|
# [auth_openidconnect]
|
|
# issuer_url = "http://localhost:8082/auth/realms/myrealm"
|
|
# client_id = "krill"
|
|
# client_secret = "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx"
|
|
#
|
|
# That's it! For this to work you must already have configured your KeyCloak
|
|
# instance e.g. with a realm, client (with redirect URI set), users and an
|
|
# attribute mapper (to expose a custom user attribute as a "role" claim) and a
|
|
# "role" attribute for each user.

|
# Example Azure Active Directory configuration:
|
|
# ------------------------------------------------------------------------------
|
|
# This example is for a Microsoft Azure cloud Active Directory instance that
|
|
# permits only read-only and read-write access to users that login via the Krill
|
|
# web UI:
|
|
#
|
|
# [auth_openidconnect]
|
|
# issuer_url = "https://login.microsoftonline.com/xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx/v2.0"
|
|
# client_id = "yyyyyyyy-yyyy-yyyy-yyyy-yyyyyyyyyyyy"
|
|
# client_secret = "zzzzzzzz"
|
|
# extra_login_scopes = ["offline_access"]
|
|
#
|
|
# [auth_openidconnect.claims]
|
|
# id = { jmespath="name" }
|
|
# ro_role = { jmespath="resub(roles[?@ == 'gggggggg-gggg-gggg-gggg-gggggggggggg'] | [0], '^.+$', 'readonly')", dest="role" }
|
|
# rw_role = { jmespath="resub(roles[?@ == 'hhhhhhhh-hhhh-hhhh-hhhh-hhhhhhhhhhhh'] | [0], '^.+$', 'readwrite')", dest="role" }
|
|
#
|
|
# For this to work you must already have configured in the Azure portal your AD
|
|
# tenant, app registration and enterprise application settings (with redirect
|
|
# URI), users, group assignments and optional claim configuration (in the above
|
|
# example AD was configured to expose groups as roles).
|
|
#
|
|
# The JMESPath expression matches on Azure AD group GUID values, taking the
|
|
# first match it finds and then setting the "role" attribute to either readonly
|
|
# or readwrite depending on which GUID was matched. The GUIDs for your groups
|
|
# will be different than those used in this example, see your Krill log for the
|
|
# GUIDs to match on.
|
|
#
|
|
# The offline_access scope is required in order to trigger Azure Active
|
|
# Directory to issue a refresh token to Krill.

|
|
# Example Amazon Web Services Cognito configuration:
|
|
# ------------------------------------------------------------------------------
|
|
# [auth_openidconnect]
|
|
# issuer_url = "https://cognito-idp.eu-central-1.amazonaws.com/eu-central-1_xxxxxxx"
|
|
# client_id = "yyyyyyyy"
|
|
# client_secret = "zzzzzzzz"
|
|
# logout_url = "https://dddddddd.auth.eu-central-1.amazoncognito.com/logout?client_id=yyyyyyyy&logout_uri=https://your.krill.domain/"
|
|
#
|
|
# [auth_openidconnect.claims]
|
|
# role = { jmespath='''resub("cognito:groups"[?@ == 'KrillAdmins'] | [0], '^.+$', 'admin')''' }
|
|
#
|
|
# For this to work you must already have configured in the AWS Cognito console
|
|
# a group called KrillAdmins and have added the logging in user to that group.
|
|
# Otherwise the "cognito:groups" claim will not be present in the ID token
|
|
# response issued by AWS Cognito. You also need to have set a "Sign Out URL" for
|
|
# in your AWS Cognito "App client settings" which should match the value you
|
|
# use for the "logout_uri" query parameter in the logout_url Krill setting.
|
|
#
|
|
# logout_url needs to be set because AWS Cognito doesn't advertise support for
|
|
# any of the OpenID Connect logout mechanisms that Krill understands.
|
|
#
|
|
# dddddddd should be replaced by your AWS Cognito domain prefix that you
|
|
# specified in hte AWS Cognito "App integration" -> "Domain name" console
|
|
# setting. The regions in the URLs should also match those that you are using.
|
|
#
|
|
# Note the use of ''' which is needed because the Cognito groups claim contains
|
|
# a colon which is a reserved character in JMESPath identifiers.

|
|
# Example Google Cloud Platform configuration:
|
|
# ------------------------------------------------------------------------------
|
|
# [auth_openidconnect]
|
|
# issuer_url = "https://accounts.google.com/.well-known/openid-configuration"
|
|
# client_id = "xxxxxxxx.apps.googleusercontent.com"
|
|
# client_secret = "yyyyyyyy"
|
|
# extra_login_scopes = ["profile"]
|
|
#
|
|
# [auth_openidconnect.claims]
|
|
# role = { jmespath='''recap(resub(picture, '^.+photo\.jpg$', 'admin'), '(admin)')''' }
|
|
#
|
|
# For this to work you must already have created Credentials in the Google
|
|
# developer console and have set the redirect URI to your Krill API
|
|
# /auth/callback public URL.
|
|
#
|
|
# In this example we have included the ".well-known/..." part of the issuer_url
|
|
# to demonstrate that Krill will accept the URL with or without it.
|
|
#
|
|
# ''' is used to ensure that characters in the regular expression don't conflict
|
|
# with JMESPath reserved characters. The JMESPath expression in this example is
|
|
# not a useful real world example as it grants "admin" rights to any Google
|
|
# account that has an associated picture whose URL ends in photo.jpg.
|
|
#
|
|
# The JMESPath expression in this example uses an outer recap() call to sanity
|
|
# check that the resulting role value is what we expect it to be. Without this
|
|
# a URL that doesn't match would pass straight through resub() unchanged. The
|
|
# recap() check is needed because you might use resub() to "clean up" values
|
|
# that in some cases don't need any cleaning and thus would still be wanted
|
|
# even though not modified.
|
|
#
|
|
# Also note that, while not visible in the configuration above, the GCP OpenID
|
|
# Connect provider advertizes an RFC 7009 OAuth 2.0 Token Revocation compatible
|
|
# `revocation_endpoint` which Krill will use to revoke the Google login token
|
|
# when the user logs out of Krill. |
