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

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. AUTHOR
