You _really_ don't want to do this. See previous traffic on this list,
and some of the documents on the (current) state of Coda security.

There is, yes. We're currently running with it. It allows users who have
Kerberos principals for the realm to gain coda tokens. Users still have to
run a command to do so however.

I think it would be possible to write a PAM module which will allow an
already authenticated user to pick up Coda tokens on login. Writing something
like this is on my list of things to do - unless anyone else wants to beat
me to it (and, yes, I know you could just put 'clog' in a shell start up,
but that's hardly the point ...)

Cheers,

Simon.
