36: =head1 SYNOPSIS
37:

40: <Location /adm/roles>
41: PerlAccessHandler Apache::lonacc
42: SetHandler perl-script

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.

2818:
2819: =head2 Choosing Roles
2820:
2821: C<lonroles> is a handler that allows a user to switch roles in
2822: mid-session. LON-CAPA attempts to work with "No Role Specified", the
2823: default role that a user has before selecting a role, as widely as
2824: possible, but certain handlers for example need specification which
2825: course they should act on, etc. Both in this scenario, and when the
2826: handler determines via C<lonnet>'s C<&allowed> function that a certain
2827: action is not allowed, C<lonroles> is used as error handler. This
2828: allows the user to select another role which may have permission to do
1.246 droeschl 2829: what they were trying to do.

2842: =head2 Role Initialization
2843:
2844: 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.
1.32 harris41 2845:
2846: =head1 INTRODUCTION
2847:
2848: This module enables a user to select what role he wishes to
2849: operate under (instructor, student, teaching assistant, course
2850: coordinator, etc). These roles are pre-established by the actions
2851: of upper-level users.
