To answer James's question, the NIS master is on a linux system. I have solved my problem. Thank you to all those that replied. My problem was not NIS related at all. It had to do with local authentication. While performing some tests, I discovered that only 8< character passwords were successfully authenticating. Any passwords >8 characters were always failing. I also found that if I only typed the first 8 characters of a 12 character password, then that user would then successfully login. This became a DES/MD5 issue. I search the RedHat errata's & found updated version of the pam program. I also saw that the version of pam between the two systems were different. Upgrading system-2 to a newer version of pam (rpm found in the 7.2 updates folder on the redhat ftp site) fixed my problem. Now, any user that logs in with a >8 passwords will correctly authenticate. -Rob > -----Original Message----- > From: redhat-list-bounces@xxxxxxxxxx > [mailto:redhat-list-bounces@xxxxxxxxxx] > Sent: Tuesday, August 24, 2004 12:29 PM > To: General Red Hat Linux discussion list > Subject: RE: NIS User account? or crypt issue? > > > > A wild guess.... > > Im pushing the boat out a bit here, so dont flame me.... > > Is the nis master a redhat system? > > Ive seen a problem where the nis master is Solaris and when > the password is > changed on the Redhat system (workstation) the password is > screwed up.
