Problem with user on print

[Lucas Maciel de Maced]

I have a problem of print with any user, except root.

I use command:

$ lp -dPTR_NAME filename

and return this error:

"Unable to set the effective user id to 9 "

I have changed /etc/group, included the users on group lp and nothing.

I've gone in to SAM and verified that the printer is still listed as the
default, killed the spooler queue and restarted it.

I restart the server, and same error.

Any suggestions ?

exectute "id lp"

if it does not return anything then someone removed the lp username from /etc/passwd.

re-add the user
lp:*:9:7::/var/spool/lp:/sbin/sh

undo the mods to /etc/group as you just messed up the security.

check the permission too
-r-sr-xr-x 1 root bin 45056 Jul 15 2006 /bin/lp

Hi Tim Nelson, I execute the procedure:

# id lp

uid=9(lp) gid=7(lp)

# cat /etc/passwd | grep lp

lp:*:9:7::/var/spool/lp:/sbin/sh

This info are correct.

Hi Santhosh, I verify a permission, and have diff from your:

#ls -l /bin/lp
-rwxrwxrwx 1 root bin 73728 Sep 5 2006 /bin/lp

How to back the original permissons with chmod ?

chmod 4555 /bin/lp

Problem solved, changed permission from the file and restarted spooler, work.

Thanks to all.

If this file was messed up, there may be others. You can check with:
# swverify \*
