[krbdev.mit.edu #8945] krb5kdc: the 32 realms limit

<URL: https://krbdev.mit.edu/rt/Ticket/Display.html?id=8945 >

For your use case, would it be better to have a separate KDB for each realm
(implying separate storage, propagation, and backup), or have one KDB to which
realms could be added and removed?

To answer one of your questions, if you ran two separate krb5kdc processes each
with 31 -r options to get around the current 32-realm limitation, they would
have to serve different ports.
