Hi all

I hope anyone could help me out with my problem regarding the user_id settings.

I am running my mail servers just for fun and I am not a professional mail admin. After I am using postfix and dovecot for my mail servers with a mysql backend for the last 2 years I have tried to set up an installation with a ldap backend.

I followed the how-to from the “Postfix Book” and now I have always the following error message:

Couldn't drop privileges: User is missing UID (see mail_uid setting)

This error message occurs whenever I try to connect via a mail client. System emails were delivered the way I expected. So I assume postfix is working fine. The ldap search I use for user authentication is as follows:

uris = ldap://myserver.com

dn = cn=admin, dc=mydomain, dc=com

dnpass = secure

tls = no

base = ou=mailuser,dc=mydomain,dc=com

ldap_version = 3

user_attrs = pfMailMessageStore=home

user_filter = (&(objectClass=PFMailAccount)(pfMail=%u))

pass_attrs = pfClearPassword=password,pfMailMessageStore=userdb_home

pass_filter = (&(objectClass=PFMailAccount)(pfMail=%u))

default_pass_scheme = PLAIN

user_global_uid = 5000

user_global_gid = 5000

I am using dovecot 2.1.9, postfix 2.8.5 and openldap 2.4.23

I would appreciate any help or tipps.
