From the first message I noted this:
mailman02 dovecot: imap-login: Disconnected (tried to use unsupported auth
mechanism): user=<>, method=PLAIN, rip=1.1.1.1, lip=2.2.2.2, TLS, session=<QhWSqxofyAAKyAkM>
It seems that your client is not using GSSAPI, but PLAIN instead.
About your config:

In my configs I was forced to use REALM in uppercase. When I used it lowercase I had issues mainly with PAM.
auth_krb5_keytab = /etc/imap.keytab
Double-check that your keytab is correctly authorized in IPA and it's still valid. In my case I had to setup a cron to refresh the keytab. (Remember chown it, so Dovecot can read it)
