11 | lppasswd - add, change, or delete digest passwords. | |

28 | <i>lppasswd</i> adds, changes, or deletes passwords in the CUPS | |
29 | digest password file, <i>passwd.md5</i>. When run by a normal | |
30 | user, <i>lppasswd</i> will prompt for the old and new passwords. | |
31 | When run by the super-user, <i>lppasswd</i> can add new accounts | |
32 | (<i>-a username</i>), change existing accounts (<i>username</i>), | |
33 | or delete accounts (<i>-x username</i>) in the digest password | |
34 | file. Digest usernames do not have to match local UNIX usernames. | |
35 | <h2 class="title"><a name="OPTIONS">Options</a></h2> | |
36 | <i>lppasswd</i> supports the following options: | |
37 | <dl> | |
38 | <dt>-g groupname | |
39 | </dt> | |
40 | <dd></dd> | |
41 | <dd>Specifies a group other than the default system group. | |
42 | </dd> | |
43 | </dl> | |
44 | <h2 class="title"><a name="SECURITY_ISSUES">Security Issues</a></h2> | |
45 | By default, the <i>lppasswd</i> program is not installed to allow ordinary | |
46 | users to change their passwords. To enable this, the <i>lppasswd</i> command | |
47 | must be made setuid to root with the command: | |
48 | <br> | |
49 | <pre> | |
50 | chmod u+s lppasswd | |
51 | </pre> | |
52 | <p>While every attempt has been made to make <i>lppasswd</i> secure against | |
53 | exploits that could grant super-user privileges to unprivileged users, | |
54 | paranoid system administrators may wish to use Basic authentication with | |
55 | accounts managed by PAM instead. | |
