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 memberships 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 \ separated)

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 commandline 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.
