Failed to join domain: failed to set machine spn: Operations error

I have to say that I switched from Untangle to Astaro and am very impressed. I only have 1 problem. I am trying to get SSO working on and it will not join to the domain.

When I hit apply with correct credentials it DOES add a computer object in the computers OU but it does not finish. Has anyone seen this before? I get different errors for password being wrong or user not found so something else is up. Domain is Win2k8 R2.

Thank you

  • Hi, Vega, and welcome to posting here!

    The different solutions suggested by Vega and Longman both work, depending on how you have DNS configured in your network.  Anyone finding this thread may be interested in DNS Best Practice.

    Cheers - Bob

  • Hi All,

    I know it's been a long gone thread, but Seems I'm having the same issue, but may I know where to find that "Network Services-DNS Forwarders" part?? Can you give me the exact location for it? Thanks!

  • Hi Conrado and welcome to the UTM Community!

    If your question is about UTM WebAdmin, it's the 'Forwarders' tab in 'Network Services >> DNS'.

    Cheers - Bob
