I had configured the keycloak under the user federation settings as kerberos.
I had also entered the realm ,service principal and the keytab file directory as stated .
But I get the issue as : Kerberos is not set up . You cannot login
In firefox I has enabled SPNEGO as per the below docs :
http://www.microhowto.info/howto/configure_firefox_to_authenticate_using_spnego_and_kerberos.html
I am attaching from the log snippet :
2021-06-30 11:43:31,234 DEBUG [org.keycloak.authentication.AuthenticationSelectionResolver] (default task-1) Selections when trying execution 'auth-spnego' : [ authSelection - auth-spnego]

2021-06-30 11:43:31,235 TRACE [org.keycloak.authentication.authenticators.browser.SpnegoAuthenticator] (default task-1) Sending back WWW-Authenticate: Negotiate
Reference to the same issue :

Thanks in advance !
