LON-CAPA attempts to work with "No Role Specified", the +default role that a user has before selecting a role, as widely as +possible, but certain handlers for example need specification which +course they should act on, etc. Both in this scenario, and when the +handler determines via C's C<&allowed> function that a certain +action is not allowed, C is used as error handler. This +allows the user to select another role which may have permission to do +what they were trying to do. + +=begin latex + +\begin{figure} +\begin{center} +\includegraphics[width=0.45\paperwidth,keepaspectratio]{Sample_Roles_Screen} + \caption{\label{Sample_Roles_Screen}Sample Roles Screen} +\end{center} +\end{figure} + +=end latex + +=head2 Role Initialization + +The privileges for a user are established at login time and stored in the session environment. As a consequence, a new role does not become active till the next login. Handlers are able to query for privileges using C's C<&allowed> function. When a user first logs in, their role is the "common" role, which means that they have the sum of all of their privileges. During a session it might become necessary to choose a particular role, which as a consequence also limits the user to only the privileges in that particular role. + +=head1 INTRODUCTION + +This module enables a user to select what role he wishes to +operate under (instructor, student, teaching assistant, course +coordinator, etc).
