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.
89:
90: # ---------------------------------------------------- Configure general values

98: =head1 OPTIONS
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:
106: The first argument
107: specifies the user name of the domain coordinator and
108: should consist of only alphanumeric characters.
109:
110: The second argument specifies the password for the domain
111: coordinator and should only consist of printable ASCII
112: characters and be a string of length greater than 5 characters.
113:
114: =cut
115:
116: # ----------------------------------------------- So, are we invoked correctly?
117: # Two arguments or abort

156: =head1 MANUAL PROCEDURE
157:
158: There are 10 steps to a manual procedure.
159:
160: You need to decide on three pieces of information
161: to create a domain coordinator.
162:
163: * USERNAME (kermit, albert, joe, etc)
164: * DOMAIN (should be the same as lonDefDomain in /etc/httpd/conf/access.conf)
165: * PASSWORD (don't tell me)
166:
167: The examples in these instructions will be based
168: on three example pieces of information:
169:
170: * USERNAME=dc103
171: * DOMAIN=103
172: * PASSWORD=sesame
173:
174: You will also need to know your "root" password
175: and your "www" password.
176:
177: =over 4
178:
179: =item 1.
180:
181: login as root on your Linux system
182: [prompt %] su
183:
184: =cut
185:
186: # ------------------------------------------------------------ So, are we root?
187:
188: if ($< != 0) {
189: die 'You must be root in order to generate a domain coordinator.'."\n";
190: }
191:
192: =pod
193:
194: =item 2 (as root). add the user
195:
196: Command: [prompt %] /usr/sbin/useradd USERNAME
197: Example: [prompt %] /usr/sbin/useradd dc103
198:

207:
208: =item 3 (as root). enter in a password
209:
210: Command: [prompt %] passwd USERNAME
211: New UNIX password: PASSWORD
212: Retype new UNIX passwd: PASSWORD
213: Example: [prompt %] passwd dc103
214: New UNIX password: sesame
