[Samba 4.5] Very slow LDAP Queries (almost unusable), performance tunning ?
Are use using zarafaAccount=1 withing the search filters?
I use this things like this :
(&(objectClass=person)(zarafaAccount=1)(|(mail=%s)(otherMailbox=%s)))
Or for groups.
(&(objectclass=group)(zarafaAccount=1)(|(mail=%s)(otherMailbox=%s)))
That helps a lot.
! If you switch to kopano beware to change the SCHEMA and filters
zarafaAccount changed to kopanoAccount

[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.

No, that has no effect.
If you run
ldbsearch -s base -b @INDEXLIST
you will see a list of "@IDXATTR" attributes. You need to modify it so

samba4 adding an index to sam.ldb
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

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 ?
Thanks !

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

Samba4 LDAP LDB Indexes
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

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

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.

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

LDAP logins failing after installing Samba 4.4.5
Hi all,
I had an LDAP application (mailserver) running on Samba 4.1.3 which wrked flawlessly. Also using an LDAP browser with a simple bind worked OK.
I than replaced the Samba installation with version 4.5 and the LDAP functionality broke. I first thought it had to do with a non-SSL or non -TLS and though I now get an error message when doing a simple bind without encryption, activating

Hi all,
System is Centos 7 and Samba is 4.2.1 sernet version.
The database contains 120k users and 150k computers. It's size is 3.3GB on
DC01 where the imports were performed and 2.8GB on the second DC.
I was trying to index uid attribute and I have a strange behaviour.

[Oddity] SAMAccountName and 20+ chars logins...
Hai Marco,
What i did mean.
You can have 255 chars in total with these limitation's
Windows NT 4.0, Windows 95, Windows 98, and LAN Manager : 20 = sAMAccountName
Windows 2000 and up : 256 chars = sAMAccountName at alias.domain.tld ( full distinguished name )
The SAM-Account-Name attribute (also known as the pre?Windows 2000 user logon name) is limited to 256 characters in the Active
