Just do what the error message says, create a new user on the new DC. 
Every DC has a different RID pool (it is one of the ways you can 
identify on which DC an object was created), once the user is created on 
that DC, it will be replicated to all others. Creating the user will 
also initialise the DC's RID pool.

If you do not have ldbsearch on a particular DC, just install ldb-tools.
