(This is better asked in -hackers, I htink, copying there)
What platform is this? I use it with krb5 1.4.3 on Linux (slackware)
without any modifications at all. Perhaps platform specific behaviour?
The postmaster is linked to libkrb5support, but I only have "-lkrb5" in
my LIBS as generated by configure. However, if I do "ldd" on libkrb5.so
I see that one pulls in libkrb5support.

The principal name is definitly checked by the db as a valid user, and
AFAIK it always has been (do you have a reference to where it says it
The *REALM* is not checked, however. This can cause problems if you have
a multi-realm system (where the realms already trust each other, because
the KDC has to give out the service ticket) where you have the same
username existing in multiple realms representing different users.
If you're in a single realm, it's definitly secure.
