Description

Unix authentication seems to be not working.

Steps to reproduce
– Set the Authentication method as Unix
– Add a unix user
– Make sure the user is synced to Ranger (verify in users page)
– Try logging in as the user.

It just says username/password is not correct.

Increasing the debug level shows there is this exception.
