>> Did you specify --without-ldb-ldmb? Nope. I didn't specify "–enable-selftest" either. The default for this option being "no", why does "configure" stop after complaining that "–enable-selftest" requires lmdb? Maybe I'm just being stupid... It happens.

...n i'm happy with the status of 4.9.x then im moving it from the test repo to the stretch-samba49 repo. And I really suggest you wait until that happen, except when your want to test things out. Just change the repo name to : stretch-experimental If you want to test ldmb, the preparation for lmdb are done in the 4.9.x. packages. https://wiki.samba.org/index.php/Samba_4.9_Features_added/changed#New_Experimental_LMDB_LDB_backend Im not aware of an upgrade possibilty of tdb to lmdb (yet).

Hi list, are there preparations for upgrading a samba 4.8.5 to 4.9.1 via van-belle-repository to change the backend db? Is there some handwork necessary? Regards, Oliver

There is a compile time constant in LMDB lib that is too low for large samba Domain. I think you just have to upgrade LMDB. Looking at your python 3.6 I guess you are still on CentOS7, then you can get the patched lmdb here (reminder: you should only need the lmdb package for that specific bug): * http://samba.tranquil.it/centos7/sam...

...on-Windows-based computer." So I don't know if it is the dbcheck or the SPN which is wrong. Those two SPN have been produced automatically by a Windows workstation. I don't know if it is the OS upgrade from the client (win7 to win10) or if it is the upgrade of Samba (4.8 TDB to 4.9 LMDB) that created this discrepancy, but it is there... Cleaning up the SPN remove the dbcheck error. Should I fill a bugzilla entry for this? Cheers, Denis -- Denis Cardon Tranquil IT 12 avenue Jules Verne (Bat.

Hi Louis, you could use the systemd "requires=" directive to enforce, that samba/smbd is running before winbind.

Is that mentioned backend change

Hi there, I had some off list conversation with Aleksey and wanted to give an update on our findings (s. below). I'm currently preparing a test stack with ldb 1.4.0 (without lmdb support) and samba 4.8.3 build on top of it, to check whether lmdb support causes the mentioned trouble. An on a site note: When compiling ldb 1.4.0 with "--without-ldb-lmdb" a general error occurs during "make test": "make test called, but ldb was built --without-l...

It is hard to say what the problem is without detail such as the Samba version, what kind of database ldb is using (tdb or lmdb), the size of the domain, the number of active users, and the extent to which memory usage gets worse over time. Do you know why your database is 4GB? Douglas

...via an openLDAP (hiphiphuraaaa) we started with a new domain (I think it's the best way after 18 years) and now we are pushing all objects into the now domain. They getting a new storage and all the fileserver have to move anyway so the time is right for making everything new. @Andrew We took lmdb as a backend for the database together with bind9.

Hello Cristian, Well, nothing to say about your steps, these looks good. And lmdb could be disable in the sernet packages, cant say, i dont know. And only one DC has these problems or all?

Hi, I raised the functional level of my Samba 4.19 server with the commands below, the Schema update took a long time but ended successfully, however when raising the functional level with the second command the error below occurred and I was unable to complete the complete process. Can anyone tell me what could have happened or if they have experienced this? 1 - samba-tool domain schemaupgrade
