ConnectMaster needs to validate the token it receives from the ADFS. To do so, ConnectMaster needs the Thumbprint of the ADFS certificate that was used to sign the token.

To find the Thumbprint value on your ADFS server, follow the shown steps:

Open "AD FS Management"

 

Navigate to "Service -> Certificates".

Show the details of the “Token-signing” Certificate.

Copy the Thumbprint value and insert it into the appSetting adfs_thumbprint of the CmWinClient.exe.config.
