Configure /etc/devecot-ldap.conf.

hosts = svr6.xx.eu

dn = “cn=Directory Manager”

dnpass = “fdsmanagerpasswd”

ldap_version = 3

base = dc=xx, dc=eu

deref = never

scope = subtree

user_filter = (&(objectClass=mailgroup)(mgrpDeliverTo=%u))

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

default_pass_scheme = CRYPT
