Maybe I can help, I'll take a look at the source over the weekend.

Great. I don't think that you should break the protol, but in this case it
really doesn't matter cause I'm the only one receiving the request :)

I tried to install the cvs version and first off it failed to compile due
to pass_fd.c (support for TCP) so after disabling -DUSE_TCP in the
makefile it compiled ok, but when I start it I get the following error:

krixor:/usr/local/ser/sbin# ./ser -P /var/run/ser.pid -E
/usr/libexec/ld.so: Undefined symbol "_realm_column" in
ser:/usr/local/ser/lib/ser/modules/auth.so

This is on a OpenBSD 3.1 with gcc version 2.95.3

Also, It's pretty annoying that 'gmake install' overwrites the
configuration file all the time :)
