Auth and conditionals

Hi!

There's something wrong with my auth configuration and I can't 
figure out where the problem resides. I have to apply an access 
control to two directories, /admin and /webstat, for a domain 
called domain.tld.

$HTTP["host"] =~ "domain\.tld$" {

server.name                = "domain.tld"
auth.backend                = "htpasswd"
auth.backend.plain.userfile = "/usr/local/lighttpd/auth.user"


auth.require = ( "/admin" =>
                 (
                   "method"  => "basic",
                   "realm"   => "Restricted Area",
                   "require" =>"user=user1|user=user2|user=user3"
                 ),
                "/webstat" =>
                (
                   "method"  => "basic",
                   "realm"   => "Restricted Area",
                   "require" =>"user=user1|user=user2|user=user3"
                )
               )

}

After a reload of lighttpd it works for domain.tld, but other 
domains are affected too. So if I try to access 
domain2.tld/webstat, the password authentication for 
domain.tld/webstat shows up. What did I wrong?
