Signatur Averlon info
In addition to my info before, here is my ldap file.

hosts = localhost

dn = cn=aadmin,dc=averlon,dc=loc

#dnpass =

sasl_bind = no

auth_bind = no

ldap_version = 3

base = ou=user,dc=averlon,dc=loc

scope = onelevel

user_attrs = homeDirectory=home,uidNumber=uid,gidNumber=gid,
=mail=/home/vmail/%n/Maildir/

user_filter = (&(objectClass=posixAccount)(uid=%u))

pass_attrs = uid=user,userPassword=password

pass_filter = (&(objectClass=posixAccount)(uid=%u))

default_pass_scheme = MD5-CRYPT
