Hi, I can configrm that UPN issue is fixed in RHEL 7.3. That is great, thank you a lot. It looks like solution came with sssd 1.14.x right ? Anybody knows if there are plans to implement it into RHEL 6.x (ipa-client) ? Currently my ipa-clients on RHEL 6.8 (sssd 1.13.3.-22) are not able to handle that.

I have already tried that workaround and still no luck. At the moment this is showstopper for us on two different projects at two different customers. Any chance to get it patch before 7.3 arrives ?

Can you try setting: ldap_user_principal = nosuchattr subdomain_inherit = ldap_user_principal in sssd.conf's domain section on the server? (Yes, server, not client..) This should work without the workaround starting with 7.3..
