so you authorize already?  if so, what LDAP attribute (group etc) can you use to distinguish
the 2 types?  just use that as the basis for unlang

in authorize {}, just after ldap, you can do eg

if (%{LDAP-Group} == "unmanaged"){
 update control {
	Proxy-to-Realm := unmanaged

and then in proxy.cofn set up an 'unmanaged' server group to send the request to.

note, none of the above is validated/errer-free/tested, theres probably at least a few syntax errors but it
will give you the fundamental idea...
