similar to: Can gencache.tdb be deletely at will?

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?

Hi. I am running 3.0.20. 1. I would like to have an include statement pointing to user configurations. For a user, say 'mike', the following works: include = /home/mike/smb.conf But this does not: include = /home/%u/smb.conf I am using a very simple config with 'security = user'. What am I doing wrong? I cannot get any log feedback from this ('testparm' says

Folks, Our campus AD team has decided that they ... >Need to disable LM/NTLMv1 authentication support to provide greater >security and be consistent with the CITES authentication roadmap. Noble thoughts, but there hasn't been much thought of the ramifications for other, interoperable systems like Samba. I can see that modern Samba versions support NTLMv1 and NTLMv2 methods.

I run smbd 4.18.8 inside a docker container via "smbd --foreground" (see the attached config). Recently my server was abruptly restarted due to a power outage. Upon the restart it was able to successfully start the container, but the shares became inaccessible due to smbd rejecting all authentication attempts. In the logs I found: [2024/03/18 08:22:50.790021, 5]

On a fresh installed Illumos/Solaris in a VirtualBox Guest I get the following error after starting up samba 4.10: [2019/04/01 09:51:41.112485, 0] ../../lib/tdb_wrap/tdb_wrap.c:64(tdb_wrap_log) tdb(/var/samba/lock/gencache.tdb): tdb_open_ex: tdb_mutex_init failed for /var/samba/lock/gencache.tdb: Device busy [2019/04/01 09:51:41.141396, 0] ../../lib/util/become_daemon.c:136(daemon_ready)

Hi! Technical description below, but the exec summary is: Yes, we have a performance problem with gencache.

For what it’s worth you are not alone in seeing similar problems with Samba and gencache. Our site has some 110K users (university with staff & students (including former ones), and currently around 2000 active (SMB) clients connecting to 5 different Samba servers (around 400-500 clients per server). When we previously just let things “run” gencache.tdb would grow forever and authentication

Hi guys, Is it possible to join an AD domain using NT style authentication ? i.e. security = domain in smb.conf and use 'net join rpc -W [MYADDOMAIN] When I tried this I get the following error: [2006/02/22 11:56:42, 0] rpc_client/cli_pipe.c:cli_rpc_pipe_open_schannel(2641) cli_rpc_pipe_open_schannel: failed to get schannel session key from server msu adserver for domain MYADDOMAIN.

Hi everyone, I'm having an odd issue with a Samba install - it starts SIGABORTing complaining that gencache.tdb has gone missing.. ie [2007/08/09 12:52:50, 0] lib/util_tdb.c:tdb_log(662) tdb(/var/db/samba/gencache.tdb): tdb_reopen: open failed (No such file or directory) [2007/08/09 12:52:50, 0] smbd/server.c:open_sockets_smbd(572) tdb_reopen_all failed. If I recreate it and restart

The config looks ok, thats great. :-) Its not needed to stop samba running : net cache flush If you run: net cache list and have a look, then flush it and look again. You see its empty. If you need to copy the idmap than it is needed to stop samba. Can you show me an output of. dpkg -l | egrep "tevent|tdb|ldb|talloc|cmocka" Im running latest versions of these. Own compile or

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

Is it normal that the gencache.tdb should grow and grow “forever” and fill up with “RA/<hex>” posts? I’ve been investigating why our Samba 4.7.3 servers (happened with older version 4 servers too) would use such insane amounts of memory on our FreeBSD 11.1 servers (we see smbd processes using hundreds of megabytes of RAM and up to 5GB virtual memory). Anyway, one part that seems to use

Dear Samba experts, Initially we set up winbind to the following: idmap uid = 10000-20000 thinking that 10000 uids were sufficient for the number of users we would get. We also have defined our UNIX users from 20001 onwards. However, now I can see that our latest windows(idmap uid) users has uid 19123 and this troubles me. Since I cannot just "extend" the

I’m going to try to upgrade from 4.7.6 to 4.7.7 on one of our servers soon and see if things break or not. With 4.7.6 things are stable at least. Our file servers are in a Microsoft Windows domain (consisting of 6 Microsoft Windows 2016 AD servers). The graphs (logarithmic time scale) below are login times from a probe station that times a connect using “smbclient” with a Kerberos ticket and

I added LOG statements to mutex.c printing the strerror from the return values.   From   ret = pthread_mutexattr_init(&ma); in line 570   I got errorno 16 --> device busy.   But due the manual of pthread_mutex_attr_init() there should only be ENOMEM and EINVAL...   Doing gdb smbd -> run Doe not reveal anything, but I never used gdb for debugging anything. I just gave it a shot...

i've been integrating a Samba server into a mixed windows 2000/2003 authentication environment for use as a NAS device. i finally have things working for the most part, but in the process of debugging authentication i noticed an error when performing the following command: hmason@mpinas1:~$ smbclient -L localhost the error shows up when loglevel = 5 in smb.conf: Netbios name list:-
