Azure MFA With Netscaler via radius
If getting an issue with the service principal not being found or issue updating the service principal when running the AzureMfaNpsExtnConfigSetup.ps1 script to configure the NPS azure MFA plugin: create the service principal with the same appid that is generated by the script output:
Connect-MgGraph -Scopes 'Application.ReadWrite.All'
New-MgServicePrincipal -AppId <appid copied from script output> -DisplayName "Azure Multi-Factor Auth Client"
