How to make detailed logs for mod_auth_gssapi?

Question

Apache HTTP Server

Good afternoon, please tell me, I'm setting up Kerberos authorization in RedHat 8 on Apache ( https://access.redhat.com/articles/3161491 )
other browsers

But the logs are empty of it, as if there were no errors, I remember mod_auth_kerb wrote in detail what the problem is.
I have already done Loglevel debug and trace8 here, but everything is also almost unchanged.

mod_auth_gssapi can write detailed logs at all?
