I fixed it, thanks.

I also fixed the usage of dsdb_attribute_ldb_to_drsuapi function so now it returns properly.

There is still the problem with the call to dsdb_syntax_FOOBAR_ldb_to_drsuapi in source4/dsdb/schema/schema_syntax.c:735 (commit 6488afaa). The DSSYNC test passes when I remove that call.
