The nginx IMAP proxy can speak to a CGI to do IMAP authentication munging.
The CGI does whatever user lookups you need. The auth script then returns to
nginx the username, hostname, port, etc, to nginx which hands that off to the
IMAP server you specify for authentication.
At work we use a Catalyst server for this:
* Client hits nginx
* nginx hits auth_server.pl
* auth_server.pl uses the passed-in username to look up the user's IMAP/POP
server:port, and their internal account ID (which is what Cyrus uses for
authentication)
* auth_server.pl passes the above back to nginx
* nginx proxies the connection to the user's IMAP/POP server:port, using the
new acctid at domain credentials
The example on the nginx wiki seems to be pretty clear, using a simple PHP
script:
http://wiki.nginx.org/NginxImapAuthenticateWithApachePhpScript
We've been using this for a bit over two years, without issue. nginx is pretty
great, and the IMAP/POP proxying works very well.
