Unfortunately I didn’t seem to have saved one of those big gencache.tdb files (we don’t currently see them). Or at least I can’t seem to find them now… A while ago when we first discovered this I posted a message: https://lists.samba.org/archive/samba/2017-December/212577.html <https://lists.samba.org/archive/samba/2017-December/212577.html> I now notice that I never replied to a

Background: FREEBSD 11.2 - SAMBA 4.10.15 Hello everyone, Good evening/afternoon/morning. I am trying to "reuse" the TDB database to my portal, where I want to store basically 3 information: IP address , Name, TimeStamp - where IP would be the KEY and "NAME,TIMESTAMP" would be the VALUE. I am using the tdbtool to insert/store data successfully (like the example below)

Hi all, I have a midsize AD domain with some 50k users but only 100 workstations joined. Sometimes I find server CPU throttling at 100%. In order to let it drop and have smooth performance I delete cache: systemctl stop samba net cache flush systemctl start samba First of all, is it needed a samba stop to flush the cache? Even if cache flush does the job to restore performance, I am clueless

Samba V3, tdbsam backend. I've had to change the workgroup name in smb.conf on a Samba PDC (ie, I've changed the domain name). However, the old domain name still shows up in Windows PCs' "Microsoft Windows Network" (together with the new name, which works just fine). I want to remove the old domain name, and I assume it is still showing because it is still present in

Hello, I'm wondering if tdbtool is working in new samba. I have some UID's, which I have to delete but when i'm starting tdbtool, next open /usr/local/samba/var/locks/winbindd_idmap.tdb and trying to delete UID 109 for example, i get "delete failed", when I type "keys" command in tdbtool, I got all UID's GID's and SID's and what I was found on the list

Hi guys, I have a Netgear ReadyNas that has Samba v3.4.5 installed on it. I'm having trouble accessing some tdb files and I'm wondering whether the app tdbtool can be installed on its own as it seems that Netgear have pulled it out. I have windows domain users who get denied access for no reason and the events aren't being caught my the standard logs. Plus Netgear force the smb.conf

I had to remove reference to some printer drivers via tdbtool on ntdrivers.tdb. 1. Do I need to restart smbd and nmbd to make these changes take effect? 2. If I restart smbd and nmbd will connected users get disconnected?
