      Hi!

      A week trying to set up Squid 3.3.10 pkg 2.2.8, beta 3.1.20 pkg 2.1.2, 3.4 authorization for AD groups on pfSense 2.1.5.
      All set up and everything works as intended even !!!
      But the problem is that about every 2.5-3 hours, and sometimes right after you start falling off squid helper ext_ldap_group_acl.
      That tried to do:

      • Transfer line to the top of the config helper
      • Ext_ldap_group_acl run with the parameter -P and without
      • Increases the number of helper processes run to 15

      Warnings in the log:

       2015/02/05 10:27:43 kid1 | WARNING: no_suid: setuid (0): (1) Operation not permitted
WARNING! invalid error detail name: X509_V_ERR_DIFFERENT_CRL_SCOPE

      only appear in version 3.3, on the other versions do not.

      For fun, try to raise the squid 3.4 on freebsd 8.4 and pfSense 2.2, everything works smoothly, but I would not want to move until the version of the pfSense 2.2.

      Sorry for my english.
