[Dovecot] user_global_uid - tricky to set

Hola!

Dovecot should serve virtual mail users. So I've set user_global_uid and user_global_gid in dovecot_ldap.conf to vmail/vmail. Also I've commented auth the user_attrs field. Still Dovecot tries to switch to the uid that is defined in the LDAP entry.

It took me some time to figure out, that the only way to prevent this is to set user_attrs = foo=uid,bar=gid or something like this, so Dovecot doesn't have a chance to find the uid/gid. Still it will perform some LDAP lookups.

In my oppinion, Dovecot shouldn't try to get the uid/gid from LDAP if the user_attrs field is undefined.

I'm using Dovecot 1.0rc24 on Debian sid.
