commit 5e06c88de7bc4fe215c8630d9c3b6861f18d63bf
Author: Jeremy Allison <jra at samba.org>
Date: Fri Sep 2 12:22:34 2011 -0700
Part 3 of bugfix for bug #7509 - smb_acl_to_posix: ACL is invalid for set (Invalid argument)
Don't call check_owning_objs() to convert ACL_USER->ACL_USER_OBJ and
AC_GROUP->ACL_GROUP_OBJ for default (directory) ACLs, we do this separately
inside ensure_canon_entry_valid().
(cherry picked from commit c528fc5cacaae7e0e83041eb98150052b436071e)
commit 7f3a6c5631f901240d9e460b16d1df81e6f66e2d

Date: Fri Sep 2 11:58:56 2011 -0700
Part 2 of bugfix for bug #7509 - smb_acl_to_posix: ACL is invalid for set (Invalid argument)
Only map CREATOR_OWNER/CREATOR_GROUP to ACL_USER_OBJ/ACL_GROUP_OBJ in
a default(directory) ACL set.
(cherry picked from commit a5038ace24559bb02eec8262d3af5b5e78634d16)
commit 27c49f085a16da709e64e0f50df535edcb524b77
Author: Jeremy Allison <jra at samba.org>
Date: Fri Sep 2 11:21:08 2011 -0700
Part 1 of bugfix for bug #7509 - smb_acl_to_posix: ACL is invalid for set (Invalid argument)
Remove the code I added for bug "6878 - Cannot change ACL's inherit flag". It is incorrect
and causes the POSIX ACL ACL_USER_OBJ duplication.
(cherry picked from commit 2b935b49f3d975759eb1cbcf2b11bf7c9d982804)
