Hello,

 

Can you please check your Fw rules to validate that flow between our Device and you AD is open. Additional you can check that a ldap query is done when you attempt to connect with your ad credentials. Connect to your device (in cli with your root credentials) and enter the following command:

 

tcpdump -nni 0.0 host 'AD IP'

 

If configuration is the same in both device (cluster), ldap query follow the routing table so go through the same interface (you have to open FW rule from selfIF of both memebers). keep me update about this check. Regards,
