So the other day I was preparing to demo VMware horizon DaaS I was supposed to give to a customer when I ran into some issues. I was welcomed with a nice Login failure: General authentication error.
Well that is a bummer. Let me tell you how I fixed the problem.

The Error message:

VMware Horizon DaaS error message while logging in
Error message while loggin in.

Finding the problem and fixing it:

Naturally the first thing that came to mind was that I typed in the wrong password and or made a typo. To be sure i copy pasted the password from my password manager and… nope same error message.

Well the next step seems obvious, reset my password. Maybe I made an error adding my password to the password manager.

So password reset it is. After the password reset i tried again… Nope still the same error message. The next thing I tried was using the fat client, maybe something goes wrong with the webclient authentication (sounds peculiar I know). Anyway still the same error message even with the fat client.

Here is where things get really weird, when I tried to login to the login to the Horizon admin dashboard my password worked just fine!! Ok so my password works and authentication to the authentication layer (AD) also works fine.

Ok now I am puzzled and about to call in the support troops from our Ops department. But just as I was reaching out to one of my colleagues my focus was drawn to the assignments tab in the Horizon admin dashboard.
And low and behold, when examining the assignments I found that there was no assignment tied to my account. Could this be the reason for the error message?

I quickly assigned myself a VDI image and voila logging in worked again.

So there you have it no more: Login failure: General authentication error messages when logging in.

Final thoughts:

Just as a quick FYI, this is a Demo environment in which working with groups instead of direct user assignments is a quick a dirty solution. I recommend using group assignments instead of assigning users directly.
