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

[Carsten Laun-De Lellis]

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.

Mit freundlichem Gruß
