LNS - vpdn dialout question with cisco ACS

hello there,

i am trying to setup an szenaria where my LNS should created dynamically an l2tp tunnel
while requesting the tunnel parameters from the ACS for an specific group of users. (Service-Type Outbound!)

the IOS will be used is "c7200p-advipservicesk9-mz.124-4.XD10.bin"

as you can see below i have setup the required tunnel parameters:
(received while doing an "debug aaa author")

Oct 19 06:41:05.848 MET-DST: ppp1599 AAA/AUTHOR/LCP: Authorization succeeds trivially
Oct 19 06:41:06.872 MET-DST: ppp1599 PPP/AAA: Check Attr: service-type

Oct 19 06:41:06.876 MET-DST: Vi3.634 AAA/AUTHOR/LCP: Unsupported Service-Type: 5. No supported types found.

i actually did not find any reasons where the problem could be. - i guess the "unsupported service-type" means
the "Outbound" call - what is the problem that he cannot setup an l2tp tunnel?

here is the output from the "debug radius auth":

thanks for any help. - of course an static setup would be work fine, but iŽd like to prefer an dynamic setup.

thanks for any answers/suggestions
