two listeners with different "driver = " configs

Hi,

I would like to have two seperate imap listeners, with different authentication settings, but the mailstore and userbase etc will be identical.

I know I can do this:

service imap-login { inet_listener imap { port = 143 } inet_listener imap2 { port = 144 } }

But I'm unsure how to configure imap/143 with "driver = ldap" and imap2/144 with "driver = pam"

Just to explain why i would like this:

I am using pam-script-saml (https://github.com/ck-ws/pam-script-saml) to enable saml-based access to dovecot. I would like to have one listener 144 to only serve this saml authentication listener, and the regular 143 listener with driver = ldap.

Is that config possible?

Best regards, MJ
