How to determine which UID is associated with which user

Or just use id:

In Terminal.app, run:

id 501

It'll tell you the username that's associated with that ID. Substitute the appropriate ID, of course.

If the ownership is showing as numerics for the UID (or for the GID) for a Terminal.app "ls -al" command or related, then there likely isn't an associated user.

If the UID is 500 and up, it's probably a local user that's gone missing.

If 1000 or up, it was an OD/LDAP user.

If below 500, it's probably a system user that's a problem.

Exactly what has happened here, and why this has happened is probably more interesting. Encountering some sort of weird corruption in an LDAP configuration is No Fun. Some details on what you're seeing, please?

Hi

On the Server launch Terminal and issue this command:

dscl /LDAPv3/127.0.0.1 -list /Users GeneratedUID

You'll see _krb users which you can ignore and everyone else will be listed. The above is for an OD Master. For users in the local directory:

dscl . -list /Users GeneratedUID

For a specific LDAP (shared directory) user:

dscl /LDAPv3/127.0.0.1 -list /Users/theusershortname GeneratedUID

or for a local (non-shared directory) user:

dscl . -list /Users/usershortname GeneratedUID

Hi

Strange that nothing should show up? Which one did you try and how did you try it exactly?

The name that precedes the user name you've used to log in (admin) will be the computer's (your server) name. Look in the Computer Name field in the Sharing Preferences Pane. To see the server's hostname simply key in the word "hostname" without the quotes in the Terminal window.

If you're not having any luck with dscl navigate to /System/Library/CoreServices and launch Directory Utility. Click on the Directory Editor icon. From there click on whichever directory node you're interested in - either /Local/Default or /LDAPv3/127.0.0.1 (assuming an OD Master). Once you've selected your node select which container you want to view from the Viewing selection. For Users select Users, for Groups select Groups. Use the filter option to find a user. Once you see a User (or Group) you're interested in you will see the GeneratedUID or GUID for that user on the right hand side. This will match up with what you're seeing for ACL entries.

Hi

Apologies. I was looking at a 10.7 System. On your Server Launch WorkGroup Manager and enable the Inspector option. WorkGroup Manager Menu > Preferences. You should see a small bullseye icon has been added to the interface. Click on the Users Icon, select a user and click on the Inspector Tab.

Do you see the GUID now?

I can assure you the commands do work on pretty much any OS (Client or Server) going back to at least 10.5. You must be doing something wrong perhaps?

Hi

The advice I've given you will give you what you want. Additionally if you want to see a Group's GUID simply change /Users to /Groups.

Try it and you'll see for yourself.

HTH?
