Solution (#26635): LDAP paginated search may cause invalid warnings about duplicates

[TFGSUMIT]

This PR addresses the issue of LDAP paginated search causing invalid warnings about duplicates in large directories. It introduces a Server-Side Sort control to the paginated search, ensuring that search results are sorted and de-duplicated correctly.

Changes Made:

• Modified the UnboundLDAPConnector.searchPaginated() method to add a Server-Side Sort control to the LDAP search request.
• Updated the EnterpriseUnboundLDAPConnector.loadMemberResolver() method to perform the paginated search using the modified UnboundLDAPConnector.searchPaginated() method.

Testing Instructions:

1. Run the main.py script with a large LDAP directory to test the fix.
2. Verify that duplicates are no longer present in the search results.
3. Test the fix with different sort keys and page sizes to ensure that it works correctly in all scenarios.
