Issue
If you install the AuthPoint ADFS agent on a server where the locale is not set to en-US, clients see an error when they try to authenticate or use a resource that looks like this:
Exception details: Microsoft.IdentityServer.Web.WebConfigurationException: No style sheet is configured in the active theme for default locale [<locale code>]
The locale code is the language and country code and the decimal representation of that code in Windows. Example locale codes: en-GB/2057 and en-AU/3081.
Workaround/Solution
To fix this issue, you must set the language and locale of the service account that runs the ADFS service to en-US in the Windows services console.To do this:
Stop the ADFS service.Run this Powershell command to identify the SID of the service account: Get-ADUser -Identity "<service account user name>" |Select SIDUse regedit and browse to HKEY_Users\<SID>\Control Panel\International.Change the LocaleName value to en-US.Change the sCountry value to United States.Restart the ADFS service.
