For work I’ve been working on a configuration problem for the last few weeks in my spare time. We have Linux hosts that use NIS and PAM to authenticate our ftp and telnet users. For some reason local authentication works fine but NIS user authentication fails. We have other hosts setup the same way and with the same settings in all the key files (I think). I’ve been surfing the web and learning about how PAM is supposed to simplify UNIX authentication. I find all the cryptic configuration files to be not so simple. I guess it is good overall that I get a little more comfortable on Linux/UNIX systems and this is definitely helping that cause.
