I inherited this firewall, I am fairly versed with Check Point but Newbie with Sonic Wall. I have verified that indeed LDAP authentication is working, but it is not limited to the Security group I was told and would like. See attached word document with screen shots of what I believe to be the relevant settings. I saw some older Sonic Wall documents that had a setting that is what I wish I could find that basically said "Use this AD group" for authentication. The closest to that I could find was the Client Authentication under the WAN GroupVPN configuration where I have it checked to REquire authentication of VPN clients by XAUTH and I set the group to the AD group, but no luck. Thanks in advance for any help.
