Let's drop the bugs address from the CC for now, because I'm not
convinced this is our bug.

Could you quote part of dbg.log from a test run where that fails to
match? Are there any Solaris-specific changes that you've made to
libkadm5 or the testing scripts? I seem to recall seeing a Solaris
change that prefers kadmin/FQDN for the kadmin service principal.

This is not expected behavior. I've successfully run the test suite
many times on hosts with hyphens in their hostnames.
$KADM5_ADMIN_SERVICE should be set to "kadmin/admin" by tcl_kadm5.c. Is
that the case when you run the tests? If you need the kadmin service
principal name to contain the hostname in that code, it would help to
know more about the rationale.
Thanks,
