Apache::lonroles - User Roles Screen |
|
|
|
=head1 SYNOPSIS |
|
|
|
Invoked by /etc/httpd/conf/srm.conf: |
|
|
|
<Location /adm/roles> |
|
PerlAccessHandler Apache::lonacc |
|
SetHandler perl-script |
|
PerlHandler Apache::lonroles |
|
ErrorDocument 403 /adm/login |
|
ErrorDocument 500 /adm/errorhandler |
|
</Location> |
|
|
|
=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. |
