=head1 OVERVIEW |
| |
|
| |
=head2 Choosing Roles |
| |
|
| |
C<lonroles> is a handler that allows a user to switch roles in |
| |
mid-session. 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<lonnet>'s C<&allowed> function that a certain |
| |
action is not allowed, C<lonroles> 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. |

=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<lonnet>'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). These roles are pre-established by the actions |
| |
of upper-level users. |
| |
|
| |
This is part of the LearningOnline Network with CAPA project |
| |
described at http://www.lon-capa.org. |

=head1 OVERVIEW |
| |
|
| |
=head2 Choosing Roles |
| |
|
| |
C<lonroles> is a handler that allows a user to switch roles in |
| |
mid-session. 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<lonnet>'s C<&allowed> function that a certain |
| |
action is not allowed, C<lonroles> 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. |

=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<lonnet>'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). These roles are pre-established by the actions |
| |
of upper-level users. |
