34: =head1 NAME
35:
36: Apache::loncreateuser - handler to create users and custom roles
37:
38: =head1 SYNOPSIS
39:
40: Apache::loncreateuser provides an Apache handler for creating users,
41: editing their login parameters, roles, and removing roles, and
42: also creating and assigning custom roles.
43:
44: =head1 OVERVIEW
45:
46: =head2 Custom Roles
47:
48: In LON-CAPA, roles are actually collections of privileges. "Teaching
49: Assistant", "Course Coordinator", and other such roles are really just
50: collection of privileges that are useful in many circumstances.
51:
52: Creating custom roles can be done by the Domain Coordinator through
53: the Create User functionality. That screen will show all privileges
54: that can be assigned to users. For a complete list of privileges,
55: please see C</home/httpd/lonTabs/rolesplain.tab>.
56:
57: Custom role definitions are stored in the C<roles.db> file of the role
58: author.
