pam radius integration with http server

hi, I have successfully integrated PAM radius client http boa server to facilitate remote authentication. However I am facing few issues. If the number of re-tries is configured to 2 and timeout value is set to 3, it takes 24 secs to timeout when radius server is not available. Http client is making 4 connections and hence it takes 24 secs(2*3*4) to timeout. In the event of server not being reachable, http server should default to local authentication that happens only after 24 secs which is not acceptable. Is there any way I can fine tune this? Has any body dealt with this kind of issue? Please reply. Thanks, Nagaraj
