ldirectord config for web server behind authentication

Hello All,

I want to know the configuration paramters to specify authentication details
for the http site on real server, like what should be the addition
configuration in ldirectord to enable the director to consider a server
alive behind an authentication?


# Virtual Server for HTTP
virtual=192.168.6.240:80
        fallback=127.0.0.1:80
        real=192.168.6.4:80 gate
        real=192.168.6.5:80 gate
        service=http
        request="index.html"
        receive="Test Page"
        scheduler=rr
        #persistent=600
        protocol=tcp
  	checktype=negotiate

        username=something ?

        password=something  ?

Thanks a lot,



Imran.
