This is not good at all... Firstly old sssd, now crypto issues... Can you also say, will HBAC and SUDO in IPA work for trusted AD users on RHEL 5 servers if we will enable vulnerable tls?

RHEL5 uses OpenSSL crypto library which doesn't support TLS 1.1+ which is required by default by IPA 4.1. Your potential fix would be to allow tls1.0 use at the server side but you need to know what this leads to: https://access.redhat.com/articles/1294573 You seem to have issues on RHEL5 with TLS1.0+ configuration which is in use by the LDAP server: (Wed Jun 10 17:05:16 2015) [sssd[be[default]]] [sdap_process_result] (8): Trace: sh[0x15b01590], connected[1], ops[0x15b01e40], ldap[0x15b019d0] (Wed Jun 10 17:05:16 2015) [sssd[be[default]]] [sdap_connect_done] (3): START TLS result: Success(0), Start TLS request accepted.Server willing to negotiate SSL.
