Mr. Smith needs access to other networks and should be able to use all services, but session authentication is not suitable. The Security Administrator selects client authentication with HTTP. The standard authentication port for client HTTP authentication (Port 900) is already in use. The Security Administrator wants to use the Port 9001, but there are some connectivity problems. What is the reason for the connectivity problems? Give the BEST answer.
A.
The configuration of the service FW1_clntauth_http is not correct.
B.
The Security Policy is not correct.
C.
The configuration file $FWDIR/conf/fwauthd.conf is wrong.
D.
It is not possible to use any port other than the standard port 900 for the client authentication via HTTP.
