I am currently running postfix 2.6.6 on a Centos 6.3 machine. I have setup a samba 3.5.10 domain with openldap 2.4.23 as the central authentication. I am now trying to get postfix to be able to expand groups. We currently have about 50 groups, but not all of them will need to be addressable. All of them can be, just only about half will be used. I would like to be able to keep my existing group ou in ldap and let postfix check against it. That way when I add users to ldap groups they will automatically be in the email groups also. I have looked at the page here: http://www.postfix.org/LDAP_README.html#example_group but that looks like I will have to manually add all the members to the group using the postmap command. Is this right?
