From a894d6cc37c3799d478720f4340fcef57a5d0b4b Mon Sep 17 00:00:00 2001 From: Matthias Dieter Wallnöfer Date: Tue, 13 Apr 2010 09:18:33 +0200 Subject: s4:acl/descriptor LDB module - distinguish between root and default basedn The first is the forest base DN, the second the domain base DN. At the moment we assume that they are both the same but it hasn't to be so. Nadia, I would invite you to fix the outstanding parts regarding this (I added comments). --- source4/dsdb/samdb/ldb_modules/acl.c | 6 ++++++ source4/dsdb/samdb/ldb_modules/descriptor.c | 6 ++++++ 2 files changed, 12 insertions(+) diff --git a/source4/dsdb/samdb/ldb_modules/acl.c b/source4/dsdb/samdb/ldb_modules/acl.c index e02270631f..5679e11359 100644 --- a/source4/dsdb/samdb/ldb_modules/acl.c +++ b/source4/dsdb/samdb/ldb_modules/acl.c @@ -634,8 +634,10 @@ static int acl_add(struct ldb_module *module, struct ldb_request *req) ldb = ldb_module_get_ctx(module); /* Creating an NC.
