Different users having same home/mail_location?

[Peter Chiochetti]

Hello Tapia,

You are going to great lengths :) I assume, that PAM working means, 
"user" and "otheruser" are the names of system-users with the same uid, 
home etc? Then I do not see, why dovecot, all defaults and 
authenticating against PAM won't work out of the box, shouldn't it?
