When we upgrade a schema from 2008R2 to 2012R2, we want to apply all the changes in a single transaction - if we can't apply all the updates then we don't want to be left with a schema halfway in between the two. However, as we apply each LDIF update, we also want to refresh the schema. There are 2 reasons for this: 1. The adprep .LDIF files provided by Microsoft have some writes to schemaUpdateNow in them. 2. Microsoft uses attribute OIDs in their adprep .LDIF files, which Samba doesn't handle so well. However, we can replace the OIDs with the attribute's ldapDisplayName and they work fine. But to do this, we need to query the schema to map the OID to attribute name. And to query the schema successfully, the schema needs to be refreshed after the new attribute object has been added. Basically this patch avoids bailing out during the dsdb_schema_refresh() if we are writing schemaUpdateNow as part of a larger transaction.
