Microsoft Dynamics NAV - Error

(0) ShareShare
ReportReport
Posted on by Integrated Tech Sol... 5

I am having this error: The Service Principal Name (delegation) configuration has been set incorrectly. The certificate CN=NavServiceCert chain building failed. The certificate that was used has a trust chain that cannot be verified. Replace the certificate or change the certificateValidationMode. A certificate chain could not be built to a trusted root authority. Error occurs when I try to open it from a client. Can you please help me what exactly I should do?

Thanks a lotWhatsApp-Image-2022_2D00_05_2D00_23-at-1.35.16-PM.jpeg

    Hello,

    Thank you for your answer. 

    I have installed NAV18 as Windows Credentials. Then, I have created a Super User. I turned the credentials as NAVUserPass with the self -generation of cert. With the user created, it works. When I try to open it from another PC that is Client, it occurs the error attached yesterday.

    Can you help me further please? You were a huge help! :)

    Hello,

    Best is to use a SSL cert that was created via New-SelfSignedCertificate PowerShell command prompt if it must be a self signed cert. You also need to do the following when the initial error happens that you described in your post:

    Go to IIS, open Application Pools, select the correct Web Client Application Pool, open Advanced Settings. Find Process Model / Load User Profile and make sure it is False (default is True).

    Perform an IISRESET for the changes to take into effect.

    Hope this helps as well. 

    Thanks.
