Even just using openlog() + syslog() doesn't work for me.
I don't get it.

kinit works fine, but no syslog message.
This shows nothing useful either (I'm trying!):
# gdb /usr/mykrb/sbin/krb5kdc
...
(gdb) break openlog
Function "openlog" not defined.
Make breakpoint pending on future shared library load? (y or [n]) y
Breakpoint 1 (openlog) pending.
(gdb) set follow-fork-mode child
(gdb) run
Starting program: /usr/krbattest/sbin/krb5kdc

kinit on client here ...
... nothing, in fact I can't even Ctrl-C, Ctrl-Z, etc.
