+Making a LON-CAPA system work with shadow passwords (in five steps; +assuming that the linux system is configured for shadow passwords) +
+1. Get http://www.wwnet.net/~janc/software/mod_auth_external-2.1.13.tar.gz
+
+2. cd mod_auth_external/pwauth
+
+3. alter the config.h file line to match the UID of www
+#define SERVER_UIDS 500         /* user "www" */
+
+4.
+      If you have a /etc/pam.d directory, you need to create a file named
+      "pwauth" inside it.  To authenticate out of the Unix Shadow file
+      under Redhat 6.x, the /etc/pam.d/pwauth file should look something like
+      this:
+
+        auth       required     /lib/security/pam_pwdb.so shadow nullok
+        auth       required     /lib/security/pam_nologin.so
+        account    required     /lib/security/pam_pwdb.so
+
+
+5.  place pwauth in /usr/local/sbin/.
