[otrs] [OT] imap auth as for otrs agent ldap authentication

I know that it's off topic but probably the agent auth on ldap have might trigger the same idea to someone else. I've successfully configured my active directory as auth db for my agent, now my agents can connect to otrs using the otrs username (that for me is the same as active directory) and their domain password. Id like to know if there is a way to provide such sort of authentication alternative also for an imap or pop server so that my users can login to my domain, otrs, and mailbox using the same realm. Then I'll be able to consolidate all my users in active directory . Ciao AleX
