+\fBpam_localuser\&.so\fR [debug] [file=\fI/path/passwd\fR]
+.SH "DESCRIPTION"
+.PP
+pam_localuser is a PAM module to help implementing site\-wide login policies, where they typically include a subset of the network\*(Aqs users and a few accounts that are local to a particular workstation\&. Using pam_localuser and pam_wheel or pam_listfile is an effective way to restrict access to either local users and/or a subset of the network\*(Aqs users\&.
+.PP
+This could also be implemented using pam_listfile\&.so and a very short awk script invoked by cron, but it\*(Aqs common enough to have been separated out\&.
