Full Discussion: CUPS + passwd.md5 issue

CUPS + passwd.md5 issue
I posted the below question on the CUPS forums yesterday and have still not been able to find a good answer of why or if I can keep this from happening.

I have been looking for a while now and have still not found what I am looking for. Is there a way to allow multiple users to be updating the passwd.md5 file via the lpppasswd command? Everytime I make a change with user2 it overwrites the current user list that was made by user1. Also changes the ownership of the passswd.md5 file. Am I missing something or is there a way to allow multiple users to make changes that just update the file not overwrite the other users that were already in the digest file. Thanks in advance for help.

lppasswd

lppasswd(1)							    Apple Inc.							       lppasswd(1)

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  (user-
       name), 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.
