问题
I'm try to integrate Zabbix UI with Keycloak SSO, using keycloak-proxy. My setup is the following:
- Nginx is the entry point: it handles the "virtual host", forwarding the requests to keycloak-proxy.
- Keyclock-proxy is configured with client_id, client_secret, etc. to authenticate the users to Keycloak;
- Zabbix dashboard on Apache, default setup: I enable the HTTP authentication.
I've created a test user both in Keycloak and Zabbix. The authentication flow is ok: I'm redirected to KeyCloak, I do the authentication, but I always get "Login name or password is incorrect." from Zabbix UI.
What am I doing wrong? Has anyone tried to use OIDC authentication with Zabbix?
I' using Zabbix 4.0, KeyCloak 4.4, Keycloak-proxy 2.3.0.
keycloak-proxy configuration:
client-id: zabbix-client
client-secret: <secret>
discovery-url: http://keycloak.my.domain:8080/auth/realms/myrealm
enable-default-deny: true
enable-logout-redirect: true
enable-logging: true
encryption_key: <secret>
listen: 127.0.0.1:10080
redirection-url: http://testbed-zabbix.my.domain
upstream-url: http://a.b.c.d:80/zabbix
secure-cookie: false
enable-authorization-header: true
resources:
- uri: /*
roles:
- zabbix
回答1:
Zabbix expects PHP_AUTH_USER
(or REMOTE_USER
or AUTH_USER
) header with the username, but keycloak-proxy doesn't provide it. Let's use email as a username (you can use any claim from the access token in theory). Add email to the request header in the keycloak-proxy config:
add-claims:
- email
And create PHP_AUTH_USER
variable from email header in the Zabbix Apache config:
SetEnvIfNoCase X-Auth-Email "(.*)" PHP_AUTH_USER=$1
Note: Conf syntax can be incorrect because it is off the top of my head - it may need some tweaks.
BTW: there is a (hackish) user patch available - https://support.zabbix.com/browse/ZBXNEXT-4640, but keycloak-gatekeeper is a better solution
For the record: keycloak-proxy = keycloak-gatekeeper (the project was renamed and migrated to keycloak org recently)
