Mail.app with multiple accounts using Kerberos

[Ross L. Hatton]

I've been trying to get Mail.app to work simultaneously with my IMAP  
accounts at two institutions, each of which uses Kerberos  
authentication.  The best I've been able to do as of yet is to  
acquire tickets for each realm, then manually switch primary tickets  
and the online status of the mailboxes.

Is there a more  efficient way to get Mail or another program to  
correctly present the appropriate ticket to each server?

Thanks,
Ross
