NAME
       ext_unix_group_acl - Squid UNIX Group ACL helper

SYNOPSIS
       ext_unix_group_acl [-d] [-g group ] [-g group  ...] [-p] [-s]

DESCRIPTION
       ext_unix_group_acl  allows  Squid to base access controls on users mem‐
       berships in UNIX groups.

OPTIONS
       -d     Write debug info to stderr.  -g group Specifies a group name  to
	      match.

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

       -s     Strip  NT	 domain	 name  component from user names (/ or \ sepa‐
	      rated)

CONFIGURATION
       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/ext_unix_group_acl -p
	      acl usergroup1 external unix_group group1
	      acl usergroup2 external unix_group group2 group3

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

KNOWN ISSUES
       Does not understand GID aliased groups sometimes used  to  work	around
       groups  size  limitations. If you are using GID aliased groups then you
       must specify each alias by name.
