Printer setup suddenly asking for user and password

elektro80

Seems like a fair number of you guys have been recently seeing some problems with changing printers or setting up new ones in OS X 10.5.7.
You will get a prompt saying something about "lpadmin permissions" and you enter your admin user and password.. and the problem doesn´t go away.. Shocked

as this info is discarded.

And yes, I know some of you have been reinstalling the system a trillion times, and even changed disk drives and audio interfaces and RAM and what have you and still not figured out the real problem.

Anyways, what is really needed here is telling the system that it has to update the lpadmin group so it supports the GUID membership scheme. You won´t get access to the printer stuff unless you do so.

You need to start a session in Terminal ( with a user that has admin privs, then you enter this:

dseditgroup -o edit -p -a admin -t group _lpadmin

You will be promted for your admin password, you hit return and the output will look like this:

'_lpadmin' upgraded to new group format in order to support GUID membership

Not experiencing any problems yet? And running a recent version of OS X like 10.5.7?

Do this anyway. You won´t destroy the system if you do so. The output as shown above will show up if the command is needed and the upgrade is actually run. If the command is not needed then you won´t see the output and nothing is actually done.

Scared of typing this in manually? You simply copy/paste the command.

Again:

dseditgroup -o edit -p -a admin -t group _lpadmin

Hurrah! Laughing
