pam-0.77-16.14 pam_access man page is missing from both binary and src rpms. pam_access does not honor the "debug" option.
Man page is missing because it simply is not included in pam-0.77. There is README.pam_access in /usr/share/doc/pam-0.77/txts The debug option to pam_access was also implemented in later pam version than 0.77. This bug is resolved in RHEL5 pam version.
