"4" is an internal error code, it would manifest in your /var/log/secure
as "System Error".

No system errors are logged to /var/log/secure:

What state is SELinux on the client machine? Are there any AVC denials?

Selinux is in enforcing mode. No denials logged.

When upgrading to v2.2, and also when initializing a v2.2 replica we got
the following error:

        Applying LDAP updates
        ipa         : ERROR    Update failed: Object class violation: attribute 
"ipaSELinuxUserMapOrder" not allowed

so I suspect there are some problem with our LDAP schema. That might be
related to the "No SELinux user maps found" message.. I have a support
ticket open on this ipaSELinuxUserMapOrder-schema problem (00800931),
but not much progress there yet..

Upgrading to 2.2 from what version?

If there are no maps it may just mean that there are no maps, which is fine. SELinux user maps didn't work well in 6.3 anyway.

You might try: ipa-ldap-updater --ldapi /usr/share/ipa/updates/10-selinuxusermap.update
