Is it possible jabber tries to do an ldap lookup?
I am trying to install webmin on the same machine and I get this crap in

My /etc/pam.d/jabberd:
#%PAM-1.0
auth required pam_nologin.so
auth include system-auth
account include system-auth
session include system-auth
This also stopped my ssh account from loging in..
