How to process schemaUpdateNow ldap request

[Anatoliy Atanasov]

Hi metze,

I implemented the dsdb_create_prefix_mapping function and added code to handle schemaUpdateNow in rootdse (attachment). I used ldb_extended() and added new operation for it. 
The call to ldb_extended() never reached the schema_fsmo_extended(). 
The returned error is "Unable to find backend operation for extended". And the module variable in rootdse_modify() doesn't contain in its list the schema_fsmo module.

Regards, 
Anatoliy
