    Did someone implement realtime sync/replication between security directory server and MS Active Directory?

    If yes, Are there any references or documentation around it?

    You can't get true realtime - it will always involve an asynchronous connection. SDS has a changelog. When you enable it, SDS will write entries there whenever there are changes. It's very easy to write a TDI assembly line to read from the changelog (from memory there's a ChangeLog connector ) and write into AD (via LDAP or some other mechanism). You could use any mechanism that leverages LDAP to read records from the changelog and push the changes into AD (again using LDAP).

    Yes, this is how Federated Directory Server - https://www.ibm.com/support/knowledgecenter/en/SSCQGF_7.2.0/com.ibm.IBMDI.doc_7.2/fds.html - syncs between SDS and AD.

    You especially want to leverage the changelog to do this in environments with many users.  If you have 10's of thousands of records, or worse yet, hundreds of thousands of records, don't try to iterate through them all.  It takes WAY to long with TDI, especially if you have a lot going on in the AL before writing back to AD.
