- In course context the Functions menu will include a "View source" item/icon
for a published assessment item, if the user does not have rights to edit,
and either of the following are true:
(a) user has a cre priv, and content has source set to "open",
(b) user has vxc priv (View XML of assessments in course where
course owner/co-owner is author/co-author of content).
- vxc priv is assignable to custom role, including ad hoc custom roles
which can be made available to users with domain helpdesk role.

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.

3100: =head1 OVERVIEW
3101:
3102: =head2 Choosing Roles
3103:
3104: C<lonroles> is a handler that allows a user to switch roles in
3105: mid-session. LON-CAPA attempts to work with "No Role Specified", the
3106: default role that a user has before selecting a role, as widely as
3107: possible, but certain handlers for example need specification which
3108: course they should act on, etc. Both in this scenario, and when the
3109: handler determines via C<lonnet>'s C<&allowed> function that a certain
3110: action is not allowed, C<lonroles> is used as error handler. This
3111: allows the user to select another role which may have permission to do
3112: what they were trying to do.

3125: =head2 Role Initialization
3126:
3127: 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.
3128:
3129: =head1 INTRODUCTION
3130:
3131: This module enables a user to select what role he wishes to
3132: operate under (instructor, student, teaching assistant, course
3133: coordinator, etc). These roles are pre-established by the actions
3134: of upper-level users.

3137: described at http://www.lon-capa.org.
