[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 !!
We

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

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

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 ?
Thanks !

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,

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.
