Can't authenticate to Workgroup Manager (Local) as Administrator?

Try and log in as diradmin.

Use the same password that you set for the admin account when you set up the server

This also helped me at the end of a long chain of over issues - thanks

i also can't login using my own credentials even though i'm an administrator, but diradmin does work. however, after authenticating, the workgroup manager freezes for about 1 minute. after every action i try to perform the workgroup manager freezes for about a minute before carrying out the task.

I am trying to make default changes to the "Guest" account on the local machine in our reception area with Workgroup Manager. Thus, I am working on the following:

"Viewing local directory: /Local/Default. Not authenticated"

I have found the Guest User (UID 201).

I'm stuck as attempts to unlock are unsuccessful. I've tried my administrator username and password as well as "diradmin" with both my administrator password and "diradmin" with the Master Password for the computer.

I'm sure I'm doing something brainless, but need some help.

Thanks.

i ended up disabling open directory (in server admin, setting it to 'standalone server') since it is useless in our deployment, and that solved the issues i was having

Thanks, mate. A long and enduring mystery ... solved!
