- Bug 6754 LON-CAPA as LTI Provider
- Support LTI Extension: Context Memberships Service, whereby launch of
Consumer can trigger Provider to request course roster.
- Code moved from ltiauth.pm to routines in ltiutils.pm:
&get_lc_roles(), &create_user() and &enrolluser(); &create_passwd() routine
also moved.
- Code moved from &parse_roster() to &get_roster() in ltiutils.pm.
- New routines: &batchaddroster(), &datechange_check(), &store_passbackurl()
added to support roster updates, (including saving user-specific values
for: lis_result_sourcedid, used for passback of grades to Consumer.

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.

3206: =head1 OVERVIEW
3207:
3208: =head2 Choosing Roles
3209:
3210: C<lonroles> is a handler that allows a user to switch roles in
3211: mid-session. LON-CAPA attempts to work with "No Role Specified", the
3212: default role that a user has before selecting a role, as widely as
3213: possible, but certain handlers for example need specification which
3214: course they should act on, etc. Both in this scenario, and when the
3215: handler determines via C<lonnet>'s C<&allowed> function that a certain
3216: action is not allowed, C<lonroles> is used as error handler. This
3217: allows the user to select another role which may have permission to do
3218: what they were trying to do.

3231: =head2 Role Initialization
3232:
3233: 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.
3234:
3235: =head1 INTRODUCTION
3236:
3237: This module enables a user to select what role he wishes to
3238: operate under (instructor, student, teaching assistant, course
3239: coordinator, etc). These roles are pre-established by the actions
3240: of upper-level users.
