It sure be no pop-up, that is what i want.
My DC fullname is RDPtest.test.com.
I was edit the file /usr/share/zentyal/stubs/squid/squid.conf.mas changing the lines:
auth_param basic realm Zentyal HTTP proxy
auth_param basic program /usr/lib/squid/ldap_auth -v 3 -b ou=...
To:
auth_param ntlm program /usr/lib/squid/ntlm_auth -b test.com/RDPtest
auth_param ntlm children 25
#auth_param basic realm Zentyal HTTP proxy
#auth_param basic program /usr/lib/squid/ldap_auth -v 3 -b ou=...
and edit the file /usr/share/zentyal/stubs/squid/dansguardian.conf.mas changing the line:
#authplugin = '/etc/dansguardian/authplugins/proxy-ntlm.conf'
To:
authplugin = '/etc/dansguardian/authplugins/proxy-ntlm.conf'
I don't know what is error in my Zentyal.
