We need to support those in order to give correctly formatted binary blobs for things like wellKnownObjects This implementation is not ideal, as it allows for binary blobs on all DNs, whereas it should only allow them on those with a syntax of 2.5.5.7. We should clean this up in the future, but meanwhile this implementation at least gets us a working DC join of w2k8 to s4. This patch also uses a static function for marking DNs as invalid, which is very useful when debugging this code, as you can break on it in gdb. --- source4/lib/ldb/common/ldb_dn.c | 318 ++++++++++++++++++++++++++++++++++++---- source4/lib/ldb/include/ldb.h | 7 + 2 files changed, 295 insertions(+), 30 deletions(-) (limited to 'source4/lib/ldb') diff --git a/source4/lib/ldb/common/ldb_dn.c b/source4/lib/ldb/common/ldb_dn.c index 12a513fc42..798b85dc85 100644 --- a/source4/lib/ldb/common/ldb_dn.c +++ b/source4/lib/ldb/common/ldb_dn.c @@ -77,8 +77,17 @@ struct ldb_dn { unsigned int ext_comp_num; struct ldb_dn_ext_component *ext_components; + + char extra_type; + struct ldb_val extra_val; }; +/* it is helpful to be able to break on this in gdb */ +static void ldb_dn_mark_invalid(struct ldb_dn *dn) +{ + dn->invalid = true; +} + /* strdn may be NULL */ struct ldb_dn *ldb_dn_from_ldb_val(void *mem_ctx, struct ldb_context *ldb, @@ -94,6 +103,13 @@ struct ldb_dn *ldb_dn_from_ldb_val(void *mem_ctx, return NULL; } + /* if the DN starts with B: then it has a binary blob + * attached.
