 \label{Authentication}
 
 People are authenticated with a standard username and password scheme.
-LON-CAPA ships with support for LON-CAPA specific passwords, authentication
-using the UNIX authentication scheme on the server (assuming that
-user has a user account on that system), and Kerberos 4 and 5. It
-is easy to add other external authentication types to integrate with
-whatever your campus may use, and there are institutions doing this.
+LON-CAPA ships with support for the following authentication scheme:
+
+\begin{enumerate}
+\item internally authenticated: LON-CAPA specific passwords, choose this when in doubt. 
+\item system authentication: authentication using the UNIX authentication scheme on the server.  
+\item Kerberos authenticated: authentication based on either a Kerberos 4 or 5 server. 
+\item external authentication: custom authentication integrated with an authentication server other than Kerberos.
+\end{enumerate}
+
+If the student or user you are adding to LON-CAPA will be using the same accountas another system, e.g. email, then your system administrator can tell you which authentication type you should choose.  If you are creating a user that is unique only to LON-CAPA, then select internally authenticated.
