[Samba] LDAP_MATCHING_RULE_IN_CHAIN no longer working after upgrade?
Thank you Kees. On Mon, 6 Nov 2023 at 09:37, Kees van Vloten via samba <samba at lists.samba.org> wrote:> I am currently running at 4.19.2 but I have run 4.18.6 and 4.18.5.

There is undoubtedly something about my configuration that is different from others; I don't know if it's having members of groups from different OUs across the domain, or perhaps permissions that have been set over the years delegating ownership of different OUs, etc.. but it's interesting that I am seeing different behaviour between ldbsearch and ldapsearch now. (Andrew - I'm wondering if I can script startup of samba in docker containers after restoring from a domain backup, that I could call from git bisect. Do you know if anyone has scripts to do that sort of thing already? It's not impossible for me to create, of course, but it's always better to use an existing working script if there is one. So far, my git bisect calls a script that compiles each samba version and runs ldbsearch, checking for number of results returned; but based on the above findings that's always going to succeed, so I think I will need to switch to ldapsearch instead) Cheers Jonathan
