Posix Schema Support for 389 Directory Server
Windows Active Directory (AD) supports the POSIX schema (RFC 2307 and 2307bis) for user and group entries. In many cases, AD is used as the authoritative source of user and group data, including POSIX attributes. With Red Hat Enterprise Linux 6.4, Directory Server Windows Sync no longer ignores these attributes. Users are now able to synchronize POSIX attributes with Windows Sync between AD and 389 Directory Server.
When adding new user and group entries to the Directory Server, the POSIX attributes are not synced to AD. Adding new user and group entries to AD will synchronize to the Directory Server, and modifying attributes will synchronize them both ways.
