sAMAccountName is what resolved that issue. I am using unlang to have AD check my user's group membership and then I want to use ntlm_auth to authenticate.

But works the second time? (0) Group name is "VPN-Internal" (0) User found. Comparison between membership: name (resolved from DN), check: name

To fix this, do I add Auth-Type to my unlang statement? (0) ERROR: No Auth-Type found: rejecting the user via Post-Auth-Type = Reject

authenticate { Auth-Type PAP { pap }
Auth-Type CHAP { chap } Auth-Type MS-CHAP { mschap } ntlm_auth } }
This is obviously where it's failing, but authenticate also has ntlm_auth as I thought it should? Seems like I just need to tweak the authorize/authenticate sections?

You are not getting any results. The same with ldapsearch
So use an ldap explorer tool or talk to the ldap/AD expert at your site to get info about the schema. Openlap is uid, AD is usually eg sAMAccountName
Once you've got the right tag and paths it'll all work
