[krbdev.mit.edu #3064] Solaris client and 1.4 kadmind

[Sam Hartman via RT]

I'd like to confirm that we don't have an interop problem if we use
the non-rpc change password approach?

If we do open up support for this principal, we would need to make
sure that it was an AS request.  Typically we do that with KDC flags;
I would feel uncomfortable for that with a new principal and so we
would need a check in kadmind.
