# in /etc/passwd i have:

vmail:x:5000:5000::/var/mail:/bin/sh

on 192.168.0.10:389 : im using windows Active Directory with default
settings, user accounts are in Organization Unit named Users (i didnt
specify mail adresses in AD, hope its not mistake)

please help, thank you

 

okay, i changed to cyrus and it works now.. i think maybe was mistake in
user_attrs = sAMAccountName=home=/var/vmail/mydomain.cz/%$
or
(&(sAMAccountName=%Ln)(!(userAccountControl:1.2.840.113556.1.4.803:=2)))
line. thx
