Hi guys, we're using Dovecot/Postfix here for our mail system. I'd like to switch the
passdbauthentication on Dovecot from PAM over to a custom implementation. We'd prefer to have some sort of script check the password with an external IAM provider via HTTP. Is there any way we can accomplish this? The idea is to have Dovecot somehow call a script or send a username/password to some service, which checks the username/password against the identity provider and returns a “yes/no” back to Dovecot.
checkpasswordseems like it may work but I see no documentation on its API.Matthew R, AD, FSEN, FSO, FSCR Chief Director of Engineering & Chairman of the Board of Directors Library of Code sp-us matthew@staff.libraryofcode.org Hi!
Your best choice is to use a Lua script, see https://doc.dovecot.org/configuration_manual/authentication/lua_based_authen...

Another option would be to use the pam interface in Dovecot, to configure pam_script or pam_python and implement your authentication code in bash or python.
