Only standard accounts, can't create administrator account

[tovtov]

Hi everyone,
I trying to fix my brother's macbook pro.
It all started when he forgot his administrator user name and password, after trying to reset the password with the OS disk, I noticed there is no administrator account besides " System Administrator (root)" (I did reset the password for the root user but it didn't do anything).
In "Accounts" all I see is standards accounts and no administrator account, so I followed a guide to create a new administrator account ( mount -uw / ---- > rm /var/db/.AppleSetupDone ----------> shutdown -h now ) and created a new user that was suppose to be an Administrator account but it didn't work, the new user I created is standard as well.
What can I do?

Thanks,
Ben.


MacBook Pro, Mac OS X (10.5.8)

Did you try creating the account from booting up on the OS X install disc?

Strange. You can try the following as well:

1. Boot into single user mode. (Command S at power on)
2. Type: fsck -fy
3. Type: mount -uw /
4. Type: launchctl load /System/Library/LaunchDaemons/com.apple.DirectoryServices.plist
5. Type: diskutil repairPermissions /
6. Wait for it to finish repairing permissions (will take several minutes).
7. Type: dscl . -list /users
8. Locate your brother's account (or that new account you just made). Probably his firstnamelastname jumbled together, located near the bottom of the list.
9. Type: dscl . -append /Groups/admin GroupMembership <shortname>
   (Replacing <shortname> with the account name you got from step 8)
10. Restart the computer by typing: shutdown -r now
11. Log in to your brothers account, and verify that it's an admin.
