Two possible solutions:

1) requires a single login using Basic auth to the parent. shared by all
users of the child proxy.
   cache_peer .... login=Username:Password

2) permits for a variation of usernames, but Password is not
retrievable. Requires a helper that returns "OK user=Foo" when handed an
IP address and th parent proxy to accept the same password fro all users
(anonymous login with username tracking )

   external_acl_type ...
   cache_peer ... login=PASS
or
   external_acl_type ...
   cache_peer ... login=*:FixedPassword
