A .net console app that acts as an external authentication for ejabberd to an IMAP server.
To install the external authentication, download the latest binaries from the Releases and place them anywhere that is accessible by the ejabberd service.
Open the config of ejabberd and set the extauth_program variable to the path to the Imap-Auth.exe executable.
Run the Imap-Auth.exe once to generate the default config file, and edit it to point to the IMAP server you are authenticating against.
