Damn!! deleted ldap admin group

[babaton]

now i can't administrate the open directory.

Can this be rectified using the command line?

I tried serversetup to add a new admin user but got :

:xserve:/system/library/serversetup administrator$ ./serversetup -createUser adminuser adminuser password

I guess thats because theres no group to add the user to.
I'm thinking of demoting the server to standalone and then promoting to ODM again.

would that recreate the admin group?

I don't care if i lose my current groups as I've only just set this server up and don't have many.

However if anyone knows a less painfull method please let me know.....
