Hello, I have currently implemented NTLM (with winbind) in order that my users authenticate to AD 2000 servers (internet access allowed if they belong to the correct group) It NTLM is not available on the browser, then it switches to Basic Authentication. (then with login popup) I would like to replace if possible the basic authentication alternative by something safer. What do you recommend as replacement authentication solution ? Could ldap for instance be used ? For this alternative solution , having login popup is not a issue. The 'only' prerequisite to authenticate to AD groups of users ?
