In doing a text install disabling the NIS option and the other one (?) the root password was not set correctly in the /etc/passwd file. I had to boot to Linux Single and manually enter the password into the file.
Thats a bug in authconfig. It doesn't write 'unix' into the /etc/pam.d/* files, if shadow and md5 are disabled. Fix: Please have a look at /mnt/redhat/test/6.1-SAP-20000112/SRPMS/SRPMS/authconfig-2.0-3.src.rpm. It should be fixed with that version. Karsten
Think this is actually another problem. There is a bug which causes nothing to get written for the root password if you deselect shadow in authconfig. We are working on a fix for this and will have it in the final release.
Fixed in beta3.
