Mastodon如何使用SSO配置登录

Question

Mastodon是如何使用SSO配置登录的，比如带有keycloak的openid？我在Github中搜索并配置Mastodon，遵循本指南，但它不起作用。

这是我的环境变量：

OIDC_ENABLED=true
OIDC_DISPLAY_NAME=SSO
OIDC_AUTH_ENDPOINT=https://SSO_URL/realms/mastodon/.well-known/openid-configuration
OIDC_ISSUER=https://SSO_URL/realms/mastodon
OIDC_DISCOVERY=true
OIDC_SCOPE="openid,profile"
OIDC_UID_FIELD=uid
OIDC_CLIENT_ID=masto
OIDC_REDIRECT_URI=https://MASTODON_URL/auth/auth/openid_connect/callback
OIDC_SECURITY_ASSUME_EMAIL_IS_VERIFIED=true
OIDC_CLIENT_SECRET=***

我通过这个命令检查了错误日志，但是它是空的。

docker-compose logs | grep ERROR

甚至SSO按钮的文本也没有更改。

我的配置：

OIDC_ENABLED=true
OIDC_DISPLAY_NAME=My IDM
OIDC_DISCOVERY=true
OIDC_ISSUER=https://<keycloak_url>/auth/realms/<real>
OIDC_AUTH_ENDPOINT=https://<keycloak_url>/auth/realms/<real>/.well-known/openid-configuration
OIDC_SCOPE=openid,profile,email
OIDC_UID_FIELD=preferred_username
OIDC_CLIENT_ID=<client id>
OIDC_CLIENT_SECRET=<client secret>
OIDC_REDIRECT_URI=https://<mastodon URL>/auth/auth/openid_connect/callback
OIDC_SECURITY_ASSUME_EMAIL_IS_VERIFIED=true

用Mastondo 3.5.3和Keycloak 7.0.1进行测试

也许，只需更改您的OIDC_SCOPE和OIDC_UID_FIELD环境值。

我不能评论，但是Erik的建议真的很好，下面是我们在发现模式中使用Keycloak的最小配置：

# Enable OIDC
OIDC_ENABLED=true
# Name your button (ignored in current 3.5.3 but fix is done in upcoming releases)
OIDC_DISPLAY_NAME=Login with MySSO
# Where to find your Keycloak OIDC server
OIDC_ISSUER=https://<keycloak_domain>/realms/<my_realm>
# Use discovery to determing all OIDC endpoints
OIDC_DISCOVERY=true
# Scope you want to obtain from OIDC server
OIDC_SCOPE=openid,profile,email
# Field to be used for populating user's @alias
OIDC_UID_FIELD=preferred_username
# Client ID of the client you configured for Mastodon in Keycloak
OIDC_CLIENT_ID=<keycloak_client_id>
# Client secret of the client you configured for Mastodon in Keycloak (in production, use secrets Docker secrets in our case)
OIDC_CLIENT_SECRET=<keycloak_client_secret>
# Where OIDC server should come back after authentication
OIDC_REDIRECT_URI=https://<mastodon_domain>/auth/auth/openid_connect/callback
# Assume emails are verified by the OIDC server
OIDC_SECURITY_ASSUME_EMAIL_IS_VERIFIED=true

因此，唯一的不同是，由于OIDC的发现，我们不必添加OIDC_AUTH_ENDPOINT。
