freebsd-skq/eBones/krb/kntoln.c
csgr 105186eeee Initial import of eBones.
(Including all changes for FreeBSD - importing the original eBones distribution
would be too complex at this stage, since I don't have access to Piero's 
CVS.)
(If you want to include eBones in your system, don't forget to include
MAKE_EBONES in /etc/make.conf.)
(This stuff is now also suppable from braae.ru.ac.za.)

Bones originally from MIT SIPB.
Original port to FreeBSD 1.x  by Piero Serini.
Moved to FreeBSD 2.0 by Doug Rabson and Geoff Rehmet.
Nice bug fixes from Doug Rabson.

/*
* krb_kntoln converts an auth name into a local name by looking up
* the auth name in the /etc/aname file. The format of the aname
* file is:
*
* +-----+-----+-----+-----+------+----------+-------+-------+
* | anl | inl | rll | lnl | name | instance | realm | lname |
* +-----+-----+-----+-----+------+----------+-------+-------+
* | 1by | 1by | 1by | 1by | name | instance | realm | lname |
* +-----+-----+-----+-----+------+----------+-------+-------+
*
* If the /etc/aname file can not be opened it will set the
* local name to the auth name. Thus, in this case it performs as
* the identity function.
*
* The name instance and realm are passed to krb_kntoln through
* the AUTH_DAT structure (ad).
*
* Now here's what it *really* does:
*
* Given a Kerberos name in an AUTH_DAT structure, check that the
* instance is null, and that the realm is the same as the local
* realm, and return the principal's name in "lname". Return
* KSUCCESS if all goes well, otherwise KFAILURE.
