34: Apache::lonroles - User Roles Screen
35:
36: =head1 SYNOPSIS
37:
38: Invoked by /etc/httpd/conf/srm.conf:
39:
40: <Location /adm/roles>
41: PerlAccessHandler Apache::lonacc
42: SetHandler perl-script
43: PerlHandler Apache::lonroles
44: ErrorDocument 403 /adm/login
45: ErrorDocument 500 /adm/errorhandler
46: </Location>
47:
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
60: what they were trying to do.

72:
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.

3212: =head1 OVERVIEW
3213:
3214: =head2 Choosing Roles
3215:
3216: C<lonroles> is a handler that allows a user to switch roles in
3217: mid-session. LON-CAPA attempts to work with "No Role Specified", the
3218: default role that a user has before selecting a role, as widely as
3219: possible, but certain handlers for example need specification which
3220: course they should act on, etc. Both in this scenario, and when the
3221: handler determines via C<lonnet>'s C<&allowed> function that a certain
3222: action is not allowed, C<lonroles> is used as error handler. This
3223: allows the user to select another role which may have permission to do
3224: what they were trying to do.

3237: =head2 Role Initialization
3238:
3239: 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.
3240:
3241: =head1 INTRODUCTION
3242:
3243: This module enables a user to select what role he wishes to
3244: operate under (instructor, student, teaching assistant, course
3245: coordinator, etc). These roles are pre-established by the actions
3246: of upper-level users.
