It's the best working solution I have been able to come up with. Its being
monolithic makes it non-ideal, but it seems to work fine. It even parses
krb5.conf's [appdefaults] pam =3D { ... } and is easy to configure. It even
allows me to set non-default renew_timeouts and such. And it handles
ssh/gssapi just fine. (Provided the symlink hassle in /afs/.../home/...)

I was curious and installed openafs-krb5 on one machine, ran aklog in gdb
and did a stack trace after the segfault. It dies in krb5_get_host_realm()
in libkrb5.so.3. It happens krb5_get_host_realm() cannot handle an
*indented* comment within [domain_realm]! That is,

	# foo
        .tfy.utu.fi =3D TFY.UTU.FI

causes a SIGSEGV, while

# foo
        .tfy.utu.fi =3D TFY.UTU.FI

does not. The funny thing is, Heimdal's verify_krb5.conf never complains
(about that!). Who's at fault now, Heimdal's verification engine (which
uses Heimdal's libkrb5.so.17, not the above libkrb5.so.3) or libkrb5.so.3?
In either case, someone will get a bug report tomorrow, I just wish I knew
whom to send it to. The easiest thing would be "reportbug libkrb53". =3D)
Actually, I was not able to (quickly) find any information on whether
comments in krb5.conf are supported at all! I suppose they are since
Debian's default krb5.conf ships with them. (Heimdal version, once again.)

I'll go back to checking the openafs-krb5 stuff now since aklog now works.
I would also appreciate any help on making aklog compile agains Heimdal,
but it seems like a bigger thing - there are so many things to tackle.

You'be been extremely helpful already. Thank you. It is not very common to
find people as helpful as you.
