[jadmin] Virtual Hosting and External Authentication

[Joel Ebel]

I have a dilemma, and I'm looking for ways others may have fixed this 
problem, or perhaps just some ideas others may have.

The final goal is a system hosting both the cyrus-imap server and 
jabberd14.  This system will support as many as three domains, and both 
need to available for use by both jabber and cyrus.  They should have 
different namespaces such that you can have duplicate names in each domain.

My first thought was to use the xdb_auth_cpile with imap authentication, 
but it seems this only passes the username and not the domain.  To use 
virtual hosting in cyrus, you must either do it by IP (with a separate 
IP alias for each host) or by name (by appending @domain.com to the 
username).  So is there a way to pass this information to xdb_auth_cpile 
so it can support virtual hosting with the imap server for 
authentication, or any other method it supports.  Or will I just have to 
do virtual hosting by IP and run a separate instance of jabber on each IP?

Or, am I going about it all wrong?  Is there a better common ground to 
support virtual hosting and single sign-on between cyrus and jabber?
