I'm not sure we understand each other here. Yes I'm aware of "kernel share modes" and turning off

Hi! I joined a newly installed samba (4.20.1) server to a domain, - just testing things. Now I want to remove this test server from a domain, but I can't: root at svdcm2:/# samba-tool domain leave -U tls\\mjt-adm WARNING: Using passwords on command line is insecure. Installing the setproctitle python module will hide these from shortly after program start. Password for [TLS\mjt-adm]:

Yeah, I tried that one right after `samba-tool domain leave` - it complains there's no way to leave a domain if joined as a DC. I *guess* this is the error `samba-tool domain leave` faces too, just without proper error

Hi! Is it possible for windows to actually see and use symlinks on samba server? Windows NTFS does have notion of junctions and symbolic links, so when one open file A (which is a symbolic link), windows actually opens file B. Can such mechanism be used when A is on samba share? This is probably a protocol question more than samba question. Thanks, /mjt

Hi! This is a heads-up for now, more debugging to follow. I had to downgrade samba from 4.20.1 to 4.19.6 because 4.20 broke case insensitive file access entirely. Only exact case filename works, no matter which value is set in "case sensitive" parameter. In 4.19, things works again. /mjt -- GPG Key transition (from rsa2048 to rsa4096) since 2024-04-24.

Hi! We had a painful debugging session today, with a samba AS member server not being able to auth users anymore. The issue seems to be due to defect in samba internal DNS resolution as done in winbind. TL;DR: samba internal DNS client should not rely on UDP-only DNS, but should retry using TCP if TC bit is set in answer. There's a real-life issue with this simplistic DNS implementation.

Hi! I'm trying to understand how various ways to grant a file lease to (windows) clients works. Especially in context when files are being modified locally on the linux filesystem. For example, there's this wording in man smb.conf: kernel share modes ... Kernel share modes provide a minimal level of interoperability with local UNIX processes and NFS operations by

Just want to emphasize this particular bug, since it is serious enough, even if apparently this mode isn't used often. Having a samba server S, a windows client W and a linux client L, and two files on S, file1 and file2. 1. On W, mount the share and lock file1 (eg. if it is executable, start it). 2. On L, mount the share and try to remove (rm) file1. This will hang because the file

Hi folks, I have tried to get some information about what Samba version will be the default one when Debian Bookworm gets released, but without luck. Will it be 4.17, or 4.18? Or even 4.19.x? Will there be Samba backports for Bookworm? I saw a post from Michael Tokarev in this list a while ago, that there probably wont be a Samba 4.18 for Debian Bullseye. I also saw another post about

Dear all, Our department uses the linux system and we are not allowed to submit job directly.
