[Freeipa-users] RHEL 5.11 as IPA client

[Alexander Frolushkin]

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:

You seem to have issues on RHEL5 with TLS1.0+ configuration which is in use by the LDAP server:
