using ldap for general attributes

Hi, So I have a plan to use ldap to generally set attributes and use those attributes to set multiple specific attributes in radius. example: ldap server -> radius -> VPN vpngroup -> vpn filter and vpn tunnel and dhcp scope - > vpn does that make sense to do in the users file? could someone give me a general example of how they would try to do it? I was thinking in the ldap mapping file of adding a check item vpngroup (or whatever) and then using the users file to match off of that to set a reply of what i am looking for....
