dns in squid2.3stable1

I am installing squid2.3STABLE1.
I use a acl clients srcdomain .upm.es in order to accept request from
*.foo.com.
If I use the internal dns shipped with squid I get a denied/not
authorized reply when trying to connect from a client xxx.foo.com or
xxx.xxx.foo.com.
If I use dnsserver (compile with --disable-internal-dns) everything
works ok(the same squid.conf in both cases).
Am I doing something wrong? Has anybody had the same/similar problem?.
I use the H. Nordstrom set of patches. My O.S. is Solaris 2.6.

Thanks in advance.
