Xwiki + keycloak issue

Hi, good day. I’m facing an issue I’m not able to debug in a deployment with

keycloak 21

xwiki 15.1

OpenID Connect Authenticator 1.37.3

I followed step by step the configuration guide for keycloak, using the template files provided with the plugin and setting everything up as described and I get a HTTP 500 Error when keycloak sends me back to xwiki after providing my credentials

javax.servlet.ServletException: Failed to handle Resource Reference [path = authenticator/callback, endpoint = authenticator, pathSegments = [callback]]

Hi @DanielN

my guess is: there seems to be a misconfigured url anywhere in Keycloak as Callback URL. Please double check the URLs. Are all “https://” prefixes configured correctly in Keycloak?

It could also be due to non-trusted certificates.

Regards

The ‘hosts’ were deleted for the screenshot

The certificates are issued by sectigo, they aren’t self-signed.

I’ve enabled the DEBUG level in logs for the OIDC,but there is not any error there.

Solved. There was an additional ‘/’ in one keycloak URL on the properties file.

Also I had to add

http-request set-header X-Forwarded-Host %[req.hdr(Host)]

to my haproxy or the xwiki was redirecting to https://xwiki:80
