4.You’ve installed a PAM-aware restricted service and installed the appropriate /etc/pam.d/<service> file, but you can’t authenticate. What is the best place to look for problems?

Reinstall libpam and reboot; the library isn’t being seen.
Remove /etc/pam.d/<service>, change the /etc/pam.d/other modules entries from pam_deny.o to pam_accept.0 and try again.
Change all controls to optional and try again.
Look for clues in the log file where auth and authpriv messages are logged.
