This isn't what is being indicated by the logs and the behavior you suggest. If you can authenticate to the frontend as the test user, then the frontend is happy that the test user is a-ok. No authentications to the backend happen until you select a mailbox. Have you tried doing something like: imtest -u testuser -a slaveuser backend.your.dom and seeing if you can proxy authenticate that way? -Rob -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Rob Siemborski * Andrew Systems Group * Cyert Hall 207 * 412-268-7456 Research Systems Programmer * /usr/contributed Gatekeeper
