NTLM identification
Select NTLM transparent identification where possible to use the Windows NT and LAN Manager authentication protocol (NTLM) identification for all users of this policy except those whose user agent types are known not to support it—for example, Firefox on Linux. Non-supported user agents are presented with the pre-login welcome page, and users can log on using the basic authentication mechanism.
Note: NTLM transparent identification is not valid for remote users (connecting from unknown IP addresses). Such users must always authenticate with the web endpoint, single sign-on, or a valid
email address and password.
