Thanks for the reply. I have already tried successfully the setup without proxing the cas tickets and setting dovecot to login with a master password. The problem is that I need a password file with all the users and also I need the proxy feature for other applications.

You can try without the "proxy" line in pam_cas.conf and a static userdb with allow_all_users=yes (in place of ldap configuration). Hope this can help. You have some logs in /var/log/auth.log (depends of your distrib). -- Guillaume de Lafond Aqua Ray
