NAME¶
lppasswd - add, change, or delete digest passwords.
SYNOPSIS¶
lppasswd [
username ]
lppasswd -a [ -g
groupname ]
username
lppasswd -x
username
DESCRIPTION¶
lppasswd adds, changes, or deletes passwords in the CUPS digest password
file,
passwd.md5. When run by a normal user,
lppasswd will
prompt for the old and new passwords. When run by the super-user,
lppasswd can add new accounts (
-a username), change existing
accounts (
username), or delete accounts (
-x username) in the
digest password file. Digest usernames do not have to match local UNIX
usernames.
OPTIONS¶
lppasswd supports the following options:
- -g groupname
-
Specifies a group other than the default system group.
SECURITY ISSUES¶
By default, the
lppasswd program is not installed to allow ordinary users
to change their passwords. To enable this, the
lppasswd command must be
made setuid to root with the command:
chmod u+s lppasswd
While every attempt has been made to make
lppasswd secure against
exploits that could grant super-user privileges to unprivileged users,
paranoid system administrators may wish to use Basic authentication with
accounts managed by PAM instead.
