From 3137e4f2fe036824984352edf618a8eddde17c51 Mon Sep 17 00:00:00 2001 From: Stefan Metzmacher Date: Sat, 6 Jan 2007 01:13:59 +0000 Subject: r20580: pass the DSDB_CONTROL_REPLICATED_OBJECT_OID with the ldb_add request when applying replicated objects. the samldb module ignores such requests now... and the repl_meta_data module has different functions for the replicated and originating cases... metze (This used to be commit a4d5e0126cfd6135ab829f4984269e265a868a28) --- source4/dsdb/samdb/ldb_modules/repl_meta_data.c | 95 ++++++++++++++++++++----- source4/dsdb/samdb/ldb_modules/samldb.c | 5 ++ source4/dsdb/samdb/samdb.h | 5 ++ source4/torture/libnet/libnet_BecomeDC.c | 43 +++++++++-- 4 files changed, 126 insertions(+), 22 deletions(-) (limited to 'source4') diff --git a/source4/dsdb/samdb/ldb_modules/repl_meta_data.c b/source4/dsdb/samdb/ldb_modules/repl_meta_data.c index d9ad9d6e51..171af52eda 100644 --- a/source4/dsdb/samdb/ldb_modules/repl_meta_data.c +++ b/source4/dsdb/samdb/ldb_modules/repl_meta_data.c @@ -40,8 +40,11 @@ */ #include "includes.h" -#include "ldb/include/includes.h" +#include "lib/ldb/include/ldb.h" +#include "lib/ldb/include/ldb_errors.h" +#include "lib/ldb/include/ldb_private.h" #include "librpc/gen_ndr/ndr_misc.h" +#include "dsdb/samdb/samdb.h" static struct ldb_message_element *replmd_find_attribute(const struct ldb_message *msg, const char *name) { @@ -108,8 +111,24 @@ static int add_uint64_element(struct ldb_message *msg, const char *attr, uint64_ return 0;
