    Connecting Arc to a TM1 instance with security mode 3

    If your TM1 instance security is mode 3 (Windows SSO). Arc v4.1.1 introduces support for TM1 security mode 3 (NTLM and Kerberos).

    Security Mode: 3
    UseSSL is true

    Check first the following if you will be able to automatically be logged in,


    Some browsers like Firefox needs extra configuration for it to work.
