Hi Jeff,

By Multi-realm I mean "multiple realms"...  If you've used Krb5 much
you know that you can authenticate to multiple realms easily using
the kinit command.  I can do 'kinit jlockard at SI.UMICH.EDU' and then
'kinit jlockard at UMICH.EDU' to get tickets in both realms.  I would
expect that if my application recognizes Krb5 that my application
would allow me to choose the realm in which I want it to do things.

This was never a problem with Kerb95 on Windows authenticating to
Kerberos 4 servers.
