Ok, I must be misunderstanding. I understand that the multiple UIDs  
limitation relates to the fact that access to the auth-userdb socket  
is restricted, is that incorrect? Following that forward, where the  
example shows that you can set group access to the socket and change  
permissions to 0660 I took to mean you can now have multiple users so  
long as they are in the correct group (ie vmail). Which contradicts  
the statement that you cannot work with multiple UIDs.
Can you put that straight if I got it wrong?

thanks in advance, Andy.
