9 basic_getpwnam_auth
10
12 basic_getpwnam_auth allows Squid to authenticate any local user
13 accounts to validate the user name and password of Basic HTTP authenti‐
14 cation.
15
16 It uses getpwnam() and getspnam() routines for authentication.
17
18 This has the following advantages over the NCSA module:
19
20 - Allows authentication of all known local users
21
22 - Allows authentication through nsswitch.conf
23
24 - Can handle NIS(+) requests
25
26 - Can handle LDAP requests
27
28 - Can handle PAM requests

34 When used for authenticating to local UNIX shadow password databases
35 the program must be running as root or else it won't have sufficient
36 permissions to access the user password database. Such use of this pro‐
37 gram is not recommended, but if you absolutely need to then make the
38 program setuid root
39 chown root basic_getpwnam_auth
40 chmod u+s basic_getpwnam_auth
41
42 Please note that in such configurations it is also strongly recommended
43 that the program is moved into a directory where normal users cannot
44 access it, as this mode of operation will allow any local user to
45 brute-force other users passwords. Also note the program has not been
46 fully audited and the author cannot be held responsible for any secu‐
47 rity issues due to such installations.
