SharePoint and AD Federated Services


  • Hello,

    This might be more of a pure AD question than SharePoint but we have an issue with duplicated NetBios names and wonder if AD FS might be a solution.

    Our SharePoint Farm sites in a domain called and we have AD trusts with other domains which work fine. However we would like to trust some other domains but cannot do so because of a clash of NetBios names - i.e. the other domains are called and - so all three domains have the same NetBios name.

    I'm wondering whether AD FS might be a solution around this issue but have also heard that AD FS also requires unique NetBios names.

    Does anyone have any experience of using AD FS with SharePoint?

  • Hi,

    there is a property NetBIOSDomainNamesEnabled which needs to be enabled as by default the value of this property is set to 'False'. To enable this, run below mentioned PowerShell commands -

    1. get-spserviceapplication

    This will output every service application specifically the User Profile Service Application as I can assume that you need to configure UPA for which you need these NetBIOS name  to be working.

    2. $var=get-spserviceapplication -identity <GUID>

    Here <GUID> refer to the GUID you will get by running step 1.

    3. $var.NetBIOSDomainNamesEnabled

    If this is true then it is enabled else follow further steps.

    4. $var.NetBIOSDomainNamesEnabled = 'True'

    here you are setting the property to True

    5. $var.update()

    6. $var.NetBIOSDomainNamesEnabled

    This is simply running to confirm the result as 'true'.

    Once this is done, you need to make a new sync connection as the existing one will not work. So make a new sync connection for UPA and run the job.

    Also further if you want to understand ADFS, the link may help you on this -

    Hope this helps
