40: <Location /adm/roles>

48: =head1 OVERVIEW
49:
50: =head2 Choosing Roles
51:
52: C<lonroles> is a handler that allows a user to switch roles in
53: mid-session. LON-CAPA attempts to work with "No Role Specified", the
54: default role that a user has before selecting a role, as widely as
55: possible, but certain handlers for example need specification which
56: course they should act on, etc. Both in this scenario, and when the
57: handler determines via C<lonnet>'s C<&allowed> function that a certain
58: action is not allowed, C<lonroles> is used as error handler. This
59: allows the user to select another role which may have permission to do
1.246 droeschl 60: what they were trying to do.

73: =head2 Role Initialization
74:
75: 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.
76:
77: =head1 INTRODUCTION
78:
79: This module enables a user to select what role he wishes to
80: operate under (instructor, student, teaching assistant, course
81: coordinator, etc). These roles are pre-established by the actions
82: of upper-level users.
83:
84: This is part of the LearningOnline Network with CAPA project
85: described at http://www.lon-capa.org.

3739:
3740: =head2 Choosing Roles
3741:
3742: C<lonroles> is a handler that allows a user to switch roles in
3743: mid-session. LON-CAPA attempts to work with "No Role Specified", the
3744: default role that a user has before selecting a role, as widely as
3745: possible, but certain handlers for example need specification which
3746: course they should act on, etc. Both in this scenario, and when the
3747: handler determines via C<lonnet>'s C<&allowed> function that a certain
3748: action is not allowed, C<lonroles> is used as error handler. This
3749: allows the user to select another role which may have permission to do
1.246 droeschl 3750: what they were trying to do.

3763: =head2 Role Initialization
3764:
3765: 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.

3767: =head1 INTRODUCTION
3768:
3769: This module enables a user to select what role he wishes to
3770: operate under (instructor, student, teaching assistant, course
3771: coordinator, etc). These roles are pre-established by the actions
3772: of upper-level users.
