[Samba] pdbedit error

[Robert Steinmetz AIA]

Samba Version 3.6.3 on Ubuntu 12.04 tbdsam back end.

I discovered a couple of accounts we created before the Domain was 
configured was was an account named "administrator" intended to be the 
Smaba Administrator account. In order to change the domain ai ran this 
command

# pdbedit -I "DOMAINNAME" -U username

it worked on a number of accounts when I tried it on administrator I get the

# pdbedit -I "DOMAINNAME" -u administrator
Unable to modify TDB passwd: NT_STATUS_UNSUCCESSFUL!
Unable to modify entry!

# pdbedit -v -u administrator gives the following output
