external acl queue overload

rkrterada

Boa tarde. Estou configurando um squid no freebsd com ipfw. Estou tentando fazer o squid autenticar no ad 2008. Mas quando eu coloco o usuario e senha no proxy ele da a seguinte mensagem no cache.log do squid: "warning: external acl `ldap_group` queue overload. Request rejected `usuario grp_AcessoPadrao`". Alguém tem alguma idéia? Obrigado

Meu squid.conf está assim:

visible_hostname freebsd

##debug_options ALL,1

# Recommended minimum configuration:
