samba - Oct 2024 - Login to LDAP from new version FortiClientEMS

Hello Everyone

I am using samba 4.20.5 with debian backport. I have FortiClientEMS tool 
which connects to LDAP to get data. FortiClientEMS version 7.0.x worked 
with Samba without any problem. Unfortunately newer version 7.2.x no 
longer works. I noticed while examining Wireshark traffic that version 
7.0.x connects using authentication: sasl (3). New version 7.2.x 
authentication: ntlmsspNegotiate (10) and LDAP terminates the connection.


Can I configure Samba to solve my problem? I also tested on Samba 
version 4.17.x. I checked on Windows Server 2012 and 2022 and this 
problem does not occur here.

Best regards, Tomasz ?widerski

I just want to make sure that Samba LDAP does not support 
ntlmsspNegotiate authentication and I will have to switch to Windows Server?
