posix ldap authentication in samba 4

[brendan powers]

Hello,

I would like to have the samba4 dc I set up create and maintain a
posix compliant LDAP schema. I've looked around and haven't really
found anything to help me out.

As I see it there are 2 problems
1) Getting the POSIX schema added
2) Maintaining group membership, uids, and passwords.

I would really like to be able to authenticate Linux, and Mac
computers without having to use winbind.

Any help would be appreciated.
