Hi Pierri, Thank you Pierri for the response. My queries are inline [1]If you can set up replication between the two LDAP server instances then the data will be available on both instances. What if the users are getting added on external LDAP. Then i've to replicate it again? [2]If server2 suffix is different from server1 suffix, then you could use chaining. (so that request to Server1 get forwarded to request2) Can i get any documentation link for this chaining(If user1 belongs to ldapserver and ext_user is user for external_ldap. What happens if user1 is requesting will it go to external_ldap to get authenticated ?) [3] using the Pass Through Authentication plugin (In that case only the bind requests will be forwarded. But that may not be enough depending how exactly the application is checking the ldap authentication) I see that Openldap proxy option isn't there 389ds. Is there any other pass through autentication plugin. if you can you please share a link by which i can implement this option. Thank you Parimala Nitesh _______________________________________________ 389-users mailing list -- 389-users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to 389-users-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/389-users@xxxxxxxxxxxxxxxxxxxxxxx Do not reply to spam on the list, report it: https://pagure.io/fedora-infrastructure
