dovecot - Nov 2008 - Dovecot.1.1.6 Authentication problems using PAM+Kerberos

Hello,

    This is my first post and it is to consult about an issue I am having.
Here is the error I get in my logs:
dovecot-auth: pam_krb5[22949]: error resolving user name 'mike' to
uid/gid
pair
dovecot-auth: pam_krb5[22949]: error getting information about 'mike'

If I use kinit to authenticate it works with no problems. Any ideas on the
issue above..?

Thanks..!
