Hi Thomas,

Obtaining an authentication token for coda is a two step process, where clog
first contacts an auth2 server on an arbitrary server machine. (I believe it 
picks a name from /usr/coda/etc/vstab) and gets an encrypted token.

Possible problems here are:
  - auth2 daemon is not running.
  - there is no up-to-date user information.
  - auth2 daemon does not have up-to-date user information because
    updateclnt/updatesrv are not running.

Then clog contacts venus and passes the token it received. Venus then uses
this token to set up a secure connection with the server.

Possible problems why the server might reject a token:
  - clock skew between auth2-server/coda-server
  - corrupt/bad token (is that shorter than 8 characters bug still 
  - auth2-server didn't have up-to-date user information, see above.

The initial places to look for more information are:

 check if auth2/rpc2portmapper/updatesrv/updateclnt are all running.
 check /vice/auth2/AuthLog
 check /vice/srv/UpdateClntLog

on both servers for error messages.
