I use Liferay 6.2 on Debian Server and i use Windows 2008 R2 for my Active directory server.
I have problem, i want to use NTLM on my Liferay portal but i have some problems. My first problem was « Session key negotiation failed » that i think i resolve with https://issues.liferay.com/browse/LPS-15380?_ga=2.29586359.901964052.1528704599-2043614718.1528466370
but now i have an other problem in the log file : « unable to perform NTLM authentification à unable to authenticate due to communication failure with server liferay »
I use documentation to complete the argument in the portal but i don't have results. How know what is not good ? I test with different connect chain but nothing.
Help me please
