I trying settings the sasl. I installed libsasl-dev and recompile
squid_kerb_ldap. I setting the file /etc/default/saslauthd and
/etc/saslauthd.conf

Via testsaslauthd the authentication work with username and password of
Active Directory

root_at_Firewall:~/squid_kerb_ldap# testsaslauthd -u ricardo.dias -p 123456
0: OK "Success."
root_at_Firewall:~/squid_kerb_ldap#

Any Idea
