[webmin-l] Users and Groups module misfiring

[William A. <waa...@re...>]

A client of mine just reported a STRANGE problem when trying to create
new users in WebMins "Users and Groups" Module. I have spent the last
hour troubleshooting and verifying this. What follows is a description
of what is happening to the system files (/etc/passwd and /etc/shadow)
as well as the Samba user file (smbpasswd) when a new users is added and
later edited.

They are currently using Webmin 1.250


Create a new user with

id: first_last

User ID: choose text field and type 9999
select "normal password" radio button and type in "password" (no quotes)
choose primary group


Save

/etc/passwd now contains:

first_last:x:9999:6000:Test User:/home//students/first_last:/bin/false

(which is correct except for the TWO slashes between home and students)

the /etc/shadow file looks like:

first_last:$1$38139902$erEXj5Hm2wp4Dp4qUTzvO0:13172::::::

Which looks correct.


BUT, Samba's smbpasswd file contains:

first_last:9999:XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX:XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX:[U
         ]:LCT-43D6A303:

it is not wrapped in the smbpasswd file. Notice there is no password so
he can not log in to the Samba Domain controller.


But wait... Maybe I didn't actually select the "Normal Password" radio
button when I entered him - even though I did. (This is where it gets
really strange)

Go back and edit the user:

switch the "Pre encrypted passwrod" radio button to "Normal Password"
and retyp his password.

Click SAVE...


NOW...

/etc/password contains:

first_lastfirst_last:x:9999:6000:Test
User:/home//students/first_lastfirst_last:/bin/false

(not wrapped of course)

/etc/shadow contains:

first_lastfirst_last:$1$38140733$C29l/0szvz337yXUOwMB3/:13172::::::

AND SMBPASSWD CONTAINS:
first_lastfirst_last:9999:XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX:XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX:[U
         ]:LCT-43D6A641:


HHHM!   So I go re-edit the user and notice that his name appears twice
in the list of users and in the id field... so I strip off the 2nd
iteration of his name, set his password again and save:

NOW, /etc/passwd contains:

first_lastfirst_last first_last:x:9999:6000:Test
User:/home//students/first_lastfirst_last first_last:/bin/false


And so on... As it is, Webmin's "Users and Groups" module is no longer
funtional at my client's site. If there a fix, or if can I provide more
information to help solve thess issues please let me know.

Thanks.
