Sitecore Fix – XConnect/Xdb – The certificate was not found

Was getting this error continuly on a setup we had. Somehow the certificate thumbprint was not the same as the XConnect web application thumbprint.

The fix was to verify that the certificate thumbprint matched what the XConnect application was expecting.

To fix the problem

My Setup: Sitecore 9+, Windows 10 Pro

  • Find your XConnect Client certificate
    • Open MMC, click Add/Remove Snap-In
    • Choose Certificates from available snap-ins and click Add
    • In the next window select “Computer Account”, click next
      • If you don’t see “Computer Account”, you might have to open MMC with Administrator privileges
    • Select Local Computer
    • Click Finish, then OK
    • Navigate to Certificates (Local Computer) -> Personal -> Certificates
    • Double click your XConnect Client certificate
    • Click on the “Details” tab in the certificate window
    • Scroll down in the Field list to Thumbprint
  • Verify that XConnect Client certificate Thumbprint with your XConnect AppSettings.config file located under App_Config in your XConnect website location
    • Verify with this field validateCertificateThumbprint. They should match. If it does not, try and update it with the thumbprint from the XConnect Client Certificate.
    • If updating, restart you XConnect web app after you’ve made the changes

Sitecore Fix – XConnect/Xdb Unauthorized Error

Was getting the error above during our SSO process. The solution for me was changing the SSL settings in IIS for the xconnect website from Ignore to Accept.

Sharepoint – Application Server Role, Web Server (IIS) Role – Configuration Error

When installing Sharepoint 2013 on a virtual machine running Windows Server 2012 R2 I keep getting a configuration error for the Application Server Role. After reading a bunch of material and trying to install Windows updates I’ve found that the only thing necessary is to make a copy of C:\Windows\System32\ServerManager.exe and rename the copy to C:\Windows\System32\ServerManagerCMD.exe. This seems to fix my installation problems.

Make sure to close the server manager window as well if you have it open. It seems to make the installation hang if its open.

Recover lost space on a USB drive

While doing some software installations for linux I had to shrink my flash drive to a partition of 32GB. The next time I stuck in my laptop I forgot I had done that and needed to use the entire 64GB that was available. Disk management wouldn’t allow me to delete the 32GB partition so I had do the following steps.

  • Insert your USB drive
  • Open a command prompt
  • Type in “diskpart”
  • Another window will open up, type “LIST DISK”. Not which disk is your USB drive.
  • Type in “SELECT DISK 1” or whatever disk was your USB drive.
  • Assuming you only had 1 partition on that drive, type in “SELECT PARTITION 1”.
  • Then type in “DELETE PARTITION”
  • That should be it, go back to Disk Management to complete the process of creating your partitions or formatting.
