similar to: [Samba 4.5] Very slow LDAP Queries (almost unusable), performance tunning ?

Can you tell more about your setup? Is zarafa and samba on the same server for example. Which MTA are you using postfix/exim?   My top was about 150 users, and all my printers are connected also so about 200 devices do ldap searches. but my setup is split over 10+ servers ( 2 are AD DC )   So best is to tell what you can about your setup, anonimize if needed.   Greetz,   Louis

No, you have to do that manualy, or look the the samba4 ADS script for kopano ( or zarafa ) But I mostly follow the documentation.   And when i run : time ldbsearch -H /var/lib/samba/private/sam.ldb -s base -b @INDEXLIST .... real    0m0.230s user    0m0.184s sys     0m0.044s   so if yours take more that 20 sec there is something very wrong. I suggest check you samba AD database and

Zarafa is not on the same server as Samba We only have 2 AD/DC Samba 4.5 (CentOS 7) and we put required indexes on LDAP . Arround 1000 mailboxes but not all are simultaneously in use (approx 1/3 in use). MTA is postfix (and is still connected to Samba AD, this one is not causing the issue). As a workarround, we currently deployed a synchronization connector from AD to OpenLDAP. It solves the

Thank you for your message Andrew. Then .. Waiting for this improvement... :-) Indexes seem correct to me. But I'm not sure at 100% because I cannot find clear explanation regarding the searchFlags attribute value .. 1, 2, ... ? Maybe you have one ?

Hi,   I talked to Zarafa (Kopano now) support and they acknowledge that their product in combination with Samba does not scale welland is only suitable for what they call smaller setups.     Met Vriendelijke Groet, Kind Regards, Salutations,     Bart Coninckx Bits 'n Tricks BVBA   Hoge Mierdse Heide 182 2360 Oud-Turnhout tel. +32 14 480 820 gsm +32 478 88 33 08 info at bitsandtricks.com

Dear users, We are facing to a big latency issue regarding the LDAP Server (both encrypted & plain). We have a Zarafa mail server which makes a lot of queries and puts a samba process to 100% usage. This latency makes the mail server unusable.. The mail server was previously on OpenLDAP and there was not performance issues. A simple LDAP query can take up to 25 sec to perform !! We

I have a large installation >20k users. We're using samba4 for AD Authentication, and also email address validation. I'm trying to edit the @INDEXLIST in sam.ldb to add an index on otherMailbox to speed up searches (0.05 sec for indexed, vs 2.5 sec for non-indexed searches) I'm finding that when I use ldbedit to do this, it appears to add the additional @IDXATTR. However, when I

Hai, I need to add some extra indexing on my AD DB, and im not sure if what the correct/best methode is. And is there any reason i should not do this, i did search on the wiki, but could not find the info i searched for. I know the following. Checked the current index. ( source info : https://wiki.samba.org/index.php/LDB ) ldbsearch -H /var/lib/samba/private/sam.ldb -s base -b @INDEXLIST

If you run ldbsearch -s base -b @INDEXLIST you will see a list of "@IDXATTR" attributes. You need to modify it so that there is one saying:

I think you missed these in the firewall, if you allowed the "in" for the DC, you also need the OUT. 49152:65535/tcp ALLOW OUT Greetz, Louis > -----Oorspronkelijk bericht----- > Van: samba [mailto:samba-bounces at lists.samba.org] Namens > Gaetan SLONGO via samba > Verzonden: dinsdag 29 mei 2018 16:40 > Aan: Rowland Penny > CC: samba at lists.samba.org

I have a system running Samba 4 Alpha 11, and I seem to have a corrupted LDB file in my directory. (Probably the result of taking a backup without using tdbbackup). Right now, running tdbbackup on the file produces an error message similar to the following: Failed to insert into DC=WWW,DC=EXAMPLE,DC=COM.ldb.bak.tmp failed to copy DC=WWW,DC=EXAMPLE,DC=COM.ldb If I run ldbsearch -H

Hi All, We would like to know if recent developments and improvements allow to use a Microsoft Exchange infrastructure with Samba 4 as an Active Directory Controller ? Any informations about it ? Thank you very much

Hi Rowland, As said into the reply sent to Andrew, Winbind is installed, but not started by samba (this is sernet packages) Thanks ----- Mail original ----- De: "Rowland Penny via samba" <samba at lists.samba.org> À: samba at lists.samba.org Envoyé: Jeudi 24 Mai 2018 20:48:22 Objet : Re: [Samba] Samba 4.8 RODC not working On Thu, 24 May 2018 11:30:40 +0200 (CEST)
