[squid-users] Problem with the Squid 3

[Marcio Demetrio Bacci]

I have a problem with Squid 3 on Debian 8.2

When the users open your browsers, the squid asks the name and password.
Until this moment is OK, but if the users inform only the password (field
"name" not filled - in blank), the navigation is permitted.

The following is my squid.conf file:

http_port 3128
cache_mem 512 MB
cache_swap_low 80
cache_swap_high 90
maximum_object_size 512 MB
minimum_object_size 0 KB
maximum_object_size_in_memory 4096 KB
cache_replacement_policy heap LFUDA
memory_replacement_policy heap LFUDA
quick_abort_min -1 KB
detect_broken_pconn on
fqdncache_size 1024

### CACHE
refresh_pattern ^ftp:    1440    20%    10080
refresh_pattern ^gopher:    1440    0%    1440
refresh_pattern -i (/cgi-bin/|\?) 0 0%     0
refresh_pattern .        0    20%    4320
