Issues with new model.
1) authentication was hit and miss with ldap. webcit would authenticate, but IMAP would not. 2) unable to send email to users with internet mail disabled. This is a show stopper. I cannot use the email address listed as internet address without enabling all internet email. I did not get much testing beyond that as those were enough to stop me in my tracks. I will get a second system going which can be abused for testing this out more thoroughly.
