custom user lookup - how to

[Felix Nielsen]

Hi

I am looking for a way to integrate my own username/password validation - I
need to authenticate with Okta using their proxy.

Is there a way to implement this or where should I look for this in the
source code?

My initial quick-fix, was to modify the current implementation using
the /usr/local/etc/raddb/users file database

"myusername" Cleartext-Password := "mypassword"

So basically if I can find the correct function to modify it would be great

Thanks
Felix
