Re: about cyrus-imap-2.2 virtdomains

Hi Daniele,

thanks for your evaluation and the list of necessary changes.

Although, I'm currently not using cyrus 2.2.x myself, I believe this 
would be a good thing to get alligned with ISPMan.

There is currently one major drawback though - backward compatibility!

With your changes you are eliminating "uid: user_example_com" 
completely, which may have a major impact on other parts of ispman I 
currently can't overview.
Besides that I would guess that it will break "native ldap support" 
(libnss, pam) because of "@" in usernames.

Thus, I would suggest finding a way how cyrus 2.2.x can cope with both 
types of uids being present

Unfortunately, I'm currently too busy to test any of this.
So, if anybody can shed some more light on this, I will be happy to 
discuss this further.
