Hi People!
I have a RH 7.3 installed with only Samba. I am using PAM to authenthicate to the same linux box.
The authenthication is unstable, since the PAM sometimes works, sometimes not.
There are errors messages like the one below (and in the entire log file below) relating the problem to permissions. I think it is not a permission issue.
Example:
Apr 22 09:32:06 lab01 smbd: PAM [dlerror: /lib/security/pam_deny.so: cannot open shared object file: Permission denied]
Does anyone have any additional information?

Take a look at the /var/log/messages for additional information:
