Hello. We cannot login to our IPA enrolled RHEL 5.11 host using any IPA (4.1) native or AD trusted users. Seems like it fails on connection to server. SSSD logs attached. Additionally, is it ever possible now to use AD trusted users to ssh RHEL 5 servers? Logs and sssd config attached.
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:
