  • 1.  SAM NTLM Authentication

    Posted Oct 23, 2017 09:13 AM


    I configured SAM for NTLM authentication according to the System_Admin_Manual. I configured login.php for Windows Authentication, set the keys (security_ntlm_server_var and security_ntlm_authenticate_against) in SAM and changed the System configuration for security in SAM to ntlm_password.

    Client and server are in the same domain, and the user exists in SAM with the same login as the domain-login.

    Never the less I get an error on the login-page: Unknown Combination of User and Password.

    Has someone a more detailed description how to do this?

    Hi Carol,


    thanks for this link. I did it exactly as described, but still it doesn't work.

    Have you made this NTLM configuration already in the CA-Network? I tried it in my Testenvironment, but no chance to get this working.
    In SAM the configured login is in my case "herma13"

    I changed the "security_ntlm_user_search" attribute to .+\\(.+) as the one in the document doesn't fit to TANT-A01

    But I don't understand the other attributes. What are they for?

    it worked with this description in the customers environment. So I only have a problem inside the CA domain, but this doesn't matter.
