me curious who actually will update docs for heimdal and make things clear.

Please release it. OpenSSH-3.7.1p1 nor 3.6.1p2 works neither with
heimdal nor krb4. Actually, OpenSSH-3.7.1p1 does not have the krb4 code at
all, but the krb5 code does not work for me. Unfortunately, also 3.6.1p2
doe snot run with heimdal/krb4 for me.

I'm curious how is openssh-3.7.1p1 supposed to work with AFS, when there's
not krb4 support. Can you explain me that?

So how does heimdal support AFS? What are those neccessary configure flags
and krb5.conf entries?

OpenSHH-3.7.1p1 does not work on Irix and Tru64 Unix, one has to edit
config.h to get it running at least in password authmode.
To make ssh try  GSSAPI mode, one has to uncomment two GSS* lines in
sshd_config and run "ssh -o PreferredAuthentications=gssapi host" (note
trailing "s"). Unfortunately, it sshd says gssapi method is unknown and
refuses to work.



I don't believe anyone tried OpenSHH-3.7.1p1 on Irix/Tru64 even with
password autentication, but that's another story. Definitely no kerberos
