Questions about mon authentication problem!

["wildgoose" <wg4linux@xxxxxxxxxxxxxx>]

I try to build HA with lvs+mon+heartbeat,All things works fine.

but something wrong happened when I configure the mon module.

That is,I choose authtype = userfile and userfile = mydir/userfile

 in the mon.cf ,and touch a file  in mydir named userfile.Edit it

follow the instruction of mon  mannal.But when I try to login the

mon.cgi,authentication always fails.You konw ,I use shadow password in

my linux system,so I choose userfile as my authtype .
