I am not clear from this if you are using pam auth first and ldap auth
2nd, or if you are trying to use pam to do your ldap authentication for
you.  Assuming the former, I would guess that you are either failing the
auth_bind, or the attributes you are using for user_filter/pass_filter
aren't matching the username format.  I would start by checking the
settings in your dovecot-ldap.conf file...
