[squid-users] Ubuntu Server 13.10. Squid 3.3.8. WARNING: external ACL 'memberof' queue overload

Hi everyone

During configuration of LDAP basic and group authentication methods by
Squid, a came across this error (/var/log/squid3/cache.log):

Code:
WARNING: external ACL 'memberof' queue overload. Request rejected
'administrator InternetAccess'.For basic authentication I use following
piece of code:

Code:
  auth_param basic program /usr/lib/squid3/basic_ldap_auth -P -R -u cn -b
"cn=Users,dc=dot,dc=lan" ubuntu.dot.lan
  auth_param basic realm ubuntu.dot.lanThe test shows:

Administrator Pa77w0rd

OK.

For LDAP groups I use this:

Code:
  external_acl_type memberof %LOGIN
/usr/lib/squid3/ext_ldap_group_acl -P -R -K -b "dc=dot,dc=lan" -f
"(&(cn=%v)(memberOf=cn=%a,cn=Users,dc=dot,dc=lan))" -D
nslcd-service_at_dot.lan -w "Pa77w0rd" -h ubuntu.dot.lan
The test shows:

Administrator InternetAccess

OK

My ACL list has following rules:

Code:
  acl SSL_ports port 443
  acl Safe_ports port 80 # http
  acl Safe_ports port 21 # ftp
  acl Safe_ports port 443 # https
  acl Safe_ports port 70 # gopher
  acl Safe_ports port 210 # wais
  acl Safe_ports port 1025-65535 # unregistered ports
  acl Safe_ports port 280 # http-mgmt
  acl Safe_ports port 488 # gss-http
  acl Safe_ports port 591 # filemaker
  acl Safe_ports port 777 # multiling http
  acl CONNECT method CONNECT
  acl LDAP_Auth proxy_auth REQUIRED
  acl ClientNet src 192.168.1.135
  acl Block_site url_regex -i fb vk youtube
  acl InetAccess external memberof InternetAccess

And my Access/deny rules are:

Code:
  http_access allow localhost manager
  http_access deny manager
  http_access deny !Safe_ports
  http_access deny CONNECT !SSL_ports
  http_access allow localhost
  http_access deny Block_site
  http_access allow InetAccess
  http_access deny !LDAP_Auth
  http_access allow ClientNet
  http_access deny all

Where is the problem? How to solve it?

Thank you.
