New Revision: 22992

WebSVN: http://websvn.samba.org/cgi-bin/viewcvs.cgi?view=rev&root=samba&rev=22992

Log:
add a function to attach the dsdb_schema to a ldb_context
loaded from ldif files. The first file should contain
the info's about the 'prefixMap' attribute in the first ldif chunk.
The 2nd file should contain all attributes and classes.
