Could someone enlighten me real quick regarding how passwords are script and shadowed-PAM?-. My problem is that other people can not get on/logged. I can only get on as root not any of other users. Why is that? Other words the authentication fails on my MD9.1. I had a similar problem where I could not get on as root , I just reinstalled it and it worked but now it's just reversed. Thanks in advance.
