Hello,

I've installed IPsec using connections. Authentication run over FreeRADIUS. Let me a few words explain. There are two user Profile, users and devs.

1. Radius check it  in LDAP and generate an answer like this.
               
if(LDAP-Group == "devs") {
                        update reply { Class += "devs" }
    }

if(LDAP-Group == "users") {
                        update reply { Class += "users" }
    }

2. In the opnsense, under System->Access->Groups, i created the two groups. devs and users.

3. Under "VPN->IPsec->Connections" there are two connections. In "Remote Authentication" of each connection i set the Group i want to this conneciton.

This worked well since the last Update to 25.1.7_4. Into the log files i get this.

constraint check failed: group membership to 'devs' required
unacceptable: non-matching authentication done

Debug: If i take out the Group in the "Remote Authentication", then "Nothing selected" stand in the field, connect to the VPN work then.

Can some one help me? Wath is changed?
