Hello,

I'm fetching the user and auth data from LDAP, this is the string:

pass_attrs = uid=user,userPassword=password,homeDirectory=userdb_home,mailUidNumber=userdb_uid,mailGidNumber=userdb_gid,mailLocationDovecot=userdb_mail,uid=userdb_user,=userdb_quota_rule=*:bytes=%{ldap:mailQuotaBytes}, =userdb_quota_rule2=Trash:bytes=+%{ldap:mailQuotaBytesTrash}

If mailQuotaBytesTrash or mailQuotaBytes is not present, the LOGIN process does not work:

1 login user pwd 1 NO [UNAVAILABLE] Temporary authentication failure. [mailsrv2:2012-10-31 08:56:51]

• OK Waiting for authentication process to respond..

If I add those two attributes, the user can login successfully.

dovecot-2.1.10/sbin/dovecot --version 2.1.10 (9cdeab12f3e1)

The log entries:
