Is the user already in an external database?

CAVEATS
You may not add a user to a NIS or LDAP group. This must be performed on 
the corresponding server.

Similarly, if the username already exists in an external user database 
such as NIS or LDAP, useradd will deny the user account creation request.

In addition, if the user "administrator" already exists locally, you have 
to use "usermod" instead.

Note: adding a user to the root's group can be dangerous.
