Using Powershell module with Kerberos Authentication

Hello together,

I am using Kerberos authentication to log into my IcingaWeb 2.
And i used to create my Hosts by using the Powershell Module from GitHub:

Now my problem is after is started to use kerberos i can no longer use the powershell module.
I turned it off to see wheter it is related, and it is.

So does anyone know how i can fix this? Is it for example possible to use a fallback mechanism?

OS: Centos 7

Kind Regards
