Need more information on what problem(s) this causes. Are they trying to re-use the same realm name? What errors are being seen?

Comment 8 Alexander Bokovoy 2017-11-20 13:37:13 UTC
I guess we can add a logic that would check content of the krb5.keytab and decide to warn if it contains keys from a different realm than IPA. I doubt we should be erroring on them because it actually might be useful in some complex cases to allow keys from multiple realms in the same keytab (with a tuned sssd.conf to pick up proper keys by name).
