       basic_getpwnam_auth - Local Users auth helper for Squid




       basic_getpwnam_auth   allows  Squid  to  authenticate  any  local  user
       accounts  to  validate  the  user  name  and  password  of  Basic  HTTP

       It uses getpwnam() and getspnam() routines for authentication.

       This has the following advantages over the NCSA module:

       - Allows authentication of all known local users

       - Allows authentication through nsswitch.conf

       - Can handle NIS(+) requests

       - Can handle LDAP requests

       - Can handle PAM requests


              auth_param basic program /path/to/basic_getpwnam_auth
              auth_param basic children concurrency=1

       When  used  for  authenticating to local UNIX shadow password databases
       the program must be running as root or else it  won't  have  sufficient
       permissions  to  access  the  user  password database. Such use of this
       program is not recommended, but if you absolutely need to then make the
       program setuid root
              chown root basic_getpwnam_auth
              chmod u+s basic_getpwnam_auth

       Please note that in such configurations it is also strongly recommended
       that the program is moved into a directory where  normal  users  cannot
       access  it,  as  this  mode  of  operation will allow any local user to
       brute-force other users passwords. Also note the program has  not  been
       fully  audited  and  the  author  cannot  be  held  responsible for any
       security issues due to such installations.
