Portal for ArcGIS Enterprise Sign in Error

[James_Whitacre]

I am getting the following sign in error for my enterprise sign in on Portal for ArcGIS:

Invalid_Signin, This account is setup with sign in by administrator pre created users only, you need to contact account administrator. IdpUsername: '[some crazy guid]' Username: '[the same crazy guid]'

I was signed in working as normal, and then it kicked me out and I can get back in. I tried another browser, and it still did not work. Any ideas?

This was an issue on the enterprise login provider side and nothing to do with Portal for ArcGIS. My enterprise login manager was able to correct the issue and I am now able to login normally. I do not know what the issue was or how to fix it though. Thank goodness for people who know what they are doing!

I am facing the same issue. Do you know where was the exact problem in enterprise login provider? 

Thank you.

No. Sorry. My enterprise login manager was experimenting with something and accidentally took it down. He just told me he fixed it.
