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 linux system or for
55: LON-CAPA, if so aborts
56:
57: =item *
58:
59: Creates a linux system user
60:
61: =item *
62:
63: Sets password
64:
65: =item *
66:
67: Creates a LON-CAPA lonUsers directory for user
68:
69: =item *
70:
71: Sets LON-CAPA password mechanism to be "unix"
72:
73: =item *
74:
75: Set roles.hist and roles.db
76:
77: =back
78:
79: =cut
80:
81: # NOTE: I am interspersing the manual procedure with the automation.
82: # To see the manual procedure, do perldoc ./make_domain_coordinator.pl
83:
84: # This is a standalone script. It *could* alternatively use the
85: # lcuseradd script, however lcuseradd relies on certain system
86: # dependencies. make_domain_coordinator.pl should be able
87: # to run freely as possible irrespective of the status of a LON-CAPA
88: # installation.

99:
100: There are no flags to this script.
101:
102: usage: make_domain_coordinator.pl [USERNAME] [DOMAIN]
103:
104: The password is accepted through standard input
105: and should only consist of printable ASCII
106: characters and be a string of length greater than 5 characters.
107:
108: The first argument
109: specifies the user name of the domain coordinator and
110: should consist of only alphanumeric characters.
111:
112: The second argument specifies the domain of the computer
113: coordinator and should consist of only alphanumeric characters.

158: =head1 MANUAL PROCEDURE
159:
160: There are 10 steps to a manual procedure.
161:
162: You need to decide on three pieces of information
163: to create a domain coordinator.
164:
165: * USERNAME (kermit, albert, joe, etc)
166: * DOMAIN (should be the same as lonDefDomain in /etc/httpd/conf/access.conf)
167: * PASSWORD (don't tell me)
168:
169: The examples in these instructions will be based
170: on three example pieces of information:
171:
172: * USERNAME=dc103
173: * DOMAIN=103
174: * PASSWORD=sesame
175:
176: You will also need to know your "root" password
177: and your "www" password.
178:
179: =over 4
180:
181: =item 1.
182:
183: login as root on your Linux system
184: [prompt %] su
185:

187:
188: # ------------------------------------------------------------ So, are we root?
189:
190: if ($< != 0) {
191: die 'You must be root in order to generate a domain coordinator.'."\n";
192: }
193:
194: =pod
195:
196: =item 2 (as root). add the user
197:

211:
212: Command: [prompt %] passwd USERNAME
213: New UNIX password: PASSWORD
214: Retype new UNIX passwd: PASSWORD
