Keycloak Kerberos in kubernetes gssheader did not find the right tag

I’m setting up keycloak in kubernetes , I’m able to use ntlm ldap to login , now im trying to use only kerberos, I’ve put in the keytab and krb5.conf into the pod but it keep saying gssheader error , I’ve verify my keytab file using kinit and it is authenticated … any help is appreciated

Does this resolve your issue?

Summary: Check that the SPN is correct with matching hostname.

Kerberos is known to be a bit picky for principal names.
