Hello Sir
Thanks for your support and guidance, i did got some steps ahead
but there is still one problem, i successfully replicated users of AD to FDS, but still my FDS users are not synced in AD.
my DIT is something like this
dc=auth, dc=domain, dc=com
ou=People, dc=auth, dc=domain, dc=com
ou=fac, ou=People, dc=auth, dc=domain, dc=com
ou=stud, ou=People, dc=auth, dc=domain, dc=com
ou=staff, ou=People, dc=auth, dc=domain, dc=com
i have also made similar group in Windows
cn=fac, cn=users, dc=domain, dc=com
and cn=stud, cn=users, dc=domain, dc=com
one more thing my FDS is not on SSL.
Thanks
