SSL-VPN IPv4 policy with FSSO authentication (LDAP groups)

Hello,

Is that possible to create IPv4 policy using LDAP groups as source? Currently I have configured FSSO, and I am using AD groups as source in IPv4 group policy (e.g group "Group1" from active directory include user1, user2, and I create IPv4 policy where source interface is vlanXXX, source is subnet + Group1).

When I am trying to create 1:1 policy where source interface is ssl-vpn tunnel interface I am unable to add these group (only local "Firewall" group type from fortigate).
