43: =head1 DESCRIPTION
44:
45: Automates the steps for domain coordinator creation. This
46: program also describes a manual procedure (see below).
47:
48: These are the steps that are executed on the linux operating system:
49:
50: =over 4
51:
52: =item *
53:
54: Tests to see if user already exists for LON-CAPA, if not it aborts.
55:
56: =item *
57:
58: Set roles.hist and roles.db
59:
60: =back
61:
62: =cut
63:
64: # NOTE: I am interspersing the manual procedure with the automation.
65: # To see the manual procedure, do perldoc ./make_domain_coordinator.pl
66:
67: # This is a standalone script. It *could* alternatively use the
68: # lcuseradd script, however lcuseradd relies on certain system
69: # dependencies. In order to have a focused performance, I am trying
70: # to avoid system dependencies until the LON-CAPA code base becomes
71: # more robust and well-boundaried. make_domain_coordinator.pl should be able
72: # to run freely as possible, irrespective of the status of a LON-CAPA
73: # installation.

128: =head1 MANUAL PROCEDURE
129:
130: There are 2 steps to manually recreating what this script performs
131: automatically.
132:
133: You need to decide on two pieces of information
134: to create a domain coordinator.
135:
136: * USERNAME (kermit, albert, joe, etc)
137: * DOMAIN (should be a domain for thsi machine from domain.tab)
138:
139: The examples in these instructions will be based
140: on two example pieces of information:
141:
142: * USERNAME=dc103
143: * DOMAIN=103
144:
145: You will also need to know your "root" password
146: or your "www" password.
