10

12       ext_unix_group_acl  allows  Squid to base access controls on users mem‐
13       berships in UNIX groups.
14

OPTIONS

16       -d     Write debug info to stderr.  -g group Specifies a group name  to
17              match.
18
19       -p     Also match the users primary group from /etc/passwd

21       -s     Strip  NT  domain  name  component from user names (/ or \ sepa‐
22              rated)
23

CONFIGURATION

25       This squid.conf example defines two  Squid  acls.   usergroup1  matches
26       users in group1 , and usergroup2 matches users in group2 or group3
27              external_acl_type        unix_group        %LOGIN       /usr/lo‐
28              cal/squid/libexec/ext_unix_group_acl -p
29              acl usergroup1 external unix_group group1
30              acl usergroup2 external unix_group group2 group3
31
32       By default up to 11 groups can be matched in one acl (including comman‐
33       dline  specified  groups).  This  limit is defined by MAX_GROUPS in the
34       source code.
35

KNOWN ISSUES

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