WinRM and NTLM RRS feed

  • Question

  • Hello,

    I'm trying to use NTLM authentication with WinRM.

    Documentation says that NTLM is possible as part of Negotiate protocol

    • Negotiate. Negotiate is a challenge-response scheme that negotiates with the server or proxy to determine the scheme to use for authentication. For example, this parameter value allows for negotiation to determine whether the Kerberos protocol or NTLM is used.

    But when I try to use NTLM authentification - it always use Kerberos instead

    $session = New-WSManSessionOption -NoEncryption;
    Get-WSManInstance  wmi/root/cimv2/* -Enumerate -Filter "SELECT UUID from Win32_ComputerSystemProduct" -ComputerName -Authentication Negotiate -Credential\ -SessionOption $session
    I used network protocol analyzer to intercept all packets sent during execution of this cmd-let. And I found that it still uses Kerberos.
