I operate a Kerberos realm. I am not able to tell my users their
passwords. I don't have them. Kerberos stores one-way hashes of users'
passwords. I could brute force the database with sufficient time but
that is steps removed from having the actual keys in my hands.

A bad actor can do quite a bit with a compromised KDC but these things
are well known. Steps to prevent compromise are well documented as are
steps to identify compromised KDCs and mitigate the damage that they can do.
