samba - Feb 2021 - Disconnecting during many concurrent connection to OpenLDAP server

Hi everyone,

I noticed that with a large number of concurrent Samba connections (over a
thousand) to the OpenLDAP socket /var/run/ldapi there are disconnection
problems.

1. How many connections with authentication request can be established by
Samba to OpenLDAP server using single connection to socket ?
2. How long Samba keeps connections to the OpenLDAP socket ?
3. How many connections can be established to single OpenLDAP socket for
one Samba share ?
4. How many connections can be established to single OpenLDAP socket for
one Samba user ?

Thank you
