Hello Andrew,
I was trying to push the attached patch but I get errors, after a bit of
hunting I found that the problem is the unit test that do async
lsarlookupsid.
As I had no clue of why state->access_mask & LSA_POLICY_LOOKUP_NAMES
returned 1 when the openpolicy didn't set this flag I started to suspect
an error on state.
Running valgrind on samba4 + ./bin/smbtorture
ncacn_np:172.16.100.1[bigendian] rpc.lsa -U administrator%totoTATA122
with my patches yield this:
==2592== Conditional jump or move depends on uninitialised value(s)
==2592== at 0x125206CF: dcesrv_lsa_LookupSids2 (lsa_lookup.c:571)
==2592== by 0x12520D43: dcesrv_lsa_LookupSids (lsa_lookup.c:732)
==2592== by 0x12511762: lsarpc__op_dispatch (ndr_lsa_s.c:233)

==2592== by 0x71B830C: tevent_req_finish (tevent_req.c:110)
==2592==
Obviously dcesrv_lsa_get_policy_state is not returning something correct
... can you have a look because this async madness is more than I can
understand for the moment.
For the information, the patch is needed for:
1) be conform to MS documentation that is right
2) allow some client to work correctly with openchange
Thanks for your help.
Matthieu.
