Hi everybody, >>> I’m very interested in what options / solutions (if any) exist that allow >>> you to use a passwordless approach to authenticating your users against >>> imaps/pop3/smtps/submission services (tls encrypted of course)
one way to authenticate may be using Kerberos. Get your K5-Ticket-Granting-Ticket at your Kerberos server, yes: using username password, and then use this ticket during the next hours to authenticate against properly configured servers (Dovecot, Apache, ...). May be this is a hint into the direction of what might help you. Cheers, Dirk.
