With these changes, I see the following selftest failures:
Testsuite[samba3.blackbox.smbclient_auth.plain (plugin_s4_dc)]
Testsuite[samba3.blackbox.smbclient_auth.plain (plugin_s4_dc) member creds]

I have a few other comments/questions regarding the patches:

s3-auth: Finally change make_user_info_*() use a parent talloc context
- Please fix the white-space damage (and your editor)

s3-auth: Make auth_samba4 use the talloc_stackframe() context for short-term memory
- what's the purpose of this change? The existing code already frees the
  short-lived auth4_context. auth_check_password() contains a nested
  event loop, so IMO using a stackframe should be avoided.

winbindd: Ensure we do not look at rid_array before checking if it was returned
- *pnum_groups should be zeroed when num_groups == 0

selftest: Rename wbinfo_s3 to wbinfo_simple and run against plugin_s4_dc
- test_wbinfo_simple.sh usage still refers to wbinfo_s3
- fix whitespace damage in tests array

libsmb: Provide a talloc_stackframe() to external users of libsmb_setget.c
- Where are we leaking onto talloc_tos()?.
  lp_set_cmdline and setup_logging() allocate onto the NULL ctx.
- Can't we just fix the leak here instead?

Cheers, David
