To debug this, we verified that a similar error also occurred when browsing to the Advisor site (https://www.systemcenteradvisor.com/) from Internet Explorer on the Operations Manager server after choosing the option to Sign In shown below:
The errors which appeared in the Operations Manager console varied depending on whether you chose the Microsoft account option, or the Organizational account option.
Microsoft account error in the OM console:
Organizational account error in the OM console:
The following three changes were required (Internet Options, Custom Level, Security) changes were required on the server running the Operations Manager console to allow this to work correctly in the environment:
Set Scripting to Enable
Set Scripting of Java applets to enable
And set Run ActiveX controls and plug-ins to Enable
After making these changes, the Advisor Onboarding wizard was able to authenticate correctly.
