I fixed the problem.
Redhat 7.0 by default uses pam_stack.so pam module to have a central auth configuration. Sounds great doesn't it.
Last time I upgrade PAM from using a source version redhat 6.0 I didn't have any problems.
Anyway to the point - the changes to PAM configuration in redhat 7.0 depend on this pam_stack.so. Authconfig writes the system-auth file that all applications installed by redhat (that are PAM aware) are set up to refer to (using pam_stack.so).
This pam_stack.so module isn't on the PAM website and I can't guess where redhat got it from (don't have time). This module with the correct configuration was dieing in my upgraded version of pam. Now PAM configuration doesn't refer to pam_stack.so anywhere (just like Redhat 6.0) and everything works. Pam_stack.so may come from a kerberos upgrade module (that lets you work with v4 / v5 kerberos) I don't have any more time today to find out where it is.
Not that I care, but if I could find this module I could preserve redhat's default configuration.
Thanks to everyone for their help.
