Setup authentication should be ready soon for gk 2.2 too.

I think you should look deeper into radius protocol - we use
chap password, because there is no other choice. We are receiving
chap password from endpoints - and those password cannot be
decrypted because chap password is a hash. So there is not way
the gatekeeper can know clear text password. That's one of radius
drawbacks - you need to keep clear text passwords in your backend.

You can only do some tricks to encrypt/decrypt password in the database
on the fly - so they are not directly visible to database administrators etc.
It does also add some degree of protection - someone needs to steal not only
the database, but also modules with enc/dec routines for your db installation.
