An error occured during an attempt to set the SPN for the specified service account. RRS feed

  • Question

  • Hi experts,

    We are building a 2 Node ADFS farm (new setup 2012R2).

    During the first node installation we getting warning on the following:

    An error occured during an attempt to set the SPN for the specified service account.

    =============

    1. What is the impact if we ignore this warning?

    2. Any advise on how can we troubleshoot this?

    Note: we already have an existing ADFS 2.1 running with same sso fqdn. Could this be the cause?

    Thank you.

    Regards

    Chun Hai

  • Are you using the same service account for both?

    • If yes, no worry if the FQDN for both of them are the same (case of the upgrade scenario specified here: https://technet.microsoft.com/en-us/library/dn486815.aspx ).
    • If no, you can't use the same FQDN for both farms. SSO will work only for the farm using the account with the correct SPN.

    Which case are you?
