Subject: [PATCH 03/15] CONFDB: Start a ldb transaction from
sss_ldb_modify_permissive()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The reason why confdb_expand_app_domains() always fails is because we
try to do a ldb_request() without starting a ldb transaction.
When we're dealing with ldb_modify(), ldb_add(), ldb_delete() kind of
messages, those call ldb_autotransaction_request() which will start a
new transaction and treat it properly when doing the ldb_request(). In
our case that we're calling ldb_request() by our own, we must ensure
that the transaction is started and properly deal with it._
It's never been noticed because in the only place the function is used
its errors are ignored.
