NAME

       squid_unix_group - Squid UNIX Group external_acl helper

SYNOPSIS

       squid_unix_group [-g groupname] [-g groupname...] [-p]

DESCRIPTION

       This helper allows Squid to base access controls on users memberships in UNIX groups.

       -g groupname
	      Specifies a group name to match.

       -p     Also match the users primary group from /etc/passwd

EXAMPLES

       This squid.conf example defines two Squid acls. usergroup1 matches users in group1, and usergroup2 matches users in group2 or group3

	      external_acl_type unix_group %LOGIN /usr/local/squid/libexec/squid_unix_group -p

	      acl usergroup1 external unix_group group1

	      acl usergroup2 external unix_group group2 group3

NOTES

       By  default  up to 11 groups can be matched in one acl (including commandline specified groups). This limit is defined by MAX_GROUPS in the
       source code.

       must specify each alias by name.
