The NTLM method states that you can log onto a domain and web requests willbe authenticated without popup windows. Can you get the same to work with LDAP?</P><P></P><P>I have LDAP working at the moment as it authenticates users all the time. But I would like it only to popup a window if a user has not logged onto the domain.</P> Mon, 29 Mar 2004 12:46:27 GMT https://community.cisco.com/t5/application-networking/ldap-authentication-transparency/m-p/211421#M2768 adrian.watmough 2004-03-29T12:46:27Z Re: ldap Authentication Transparency https://community.cisco.com/t5/application-networking/ldap-authentication-transparency/m-p/211422#M2769 <HTML><HEAD></HEAD><BODY><P></P><P>No, basically the answer is Internet Explorer supports the use of pass through NTLM from the base operating system (XP/2000), no such method exists for LDAP (ADS) as it relies on the Kerberos tokens being issues and recognised by the the proxy device which the CE's currently don't support.
