Overview
This backend delegates the authentication to an external script.
Requires the SASL PLAIN method.
Script API specification
All "commands" sent from Erlang VM to the script are prefixed with a 2-byte unsigned integer (command length), MSB first. The script is expected to return responses in the same format.
Currently only 2 response packets are supported:
0x0000=false(for failure).0x0001=true(for success).
The following list describes packets that the script should support.
auth:<username>:<domain>:<password>- Check password.setpass:<username>:<domain>:<password>- Set password.tryregister:<username>:<domain>:<password>- Register a user.removeuser:<username>:<domain>- Remove a user.isuser:<username>:<domain>- Check if a user exists.
