VRA 7.3, ITMS 3.0, ServiceNow Istanbul and default authentication.
With the VRA_VIDM login rule marked as active, whenever a user logs into ServiceNow, they are prompted immediately to log into VRA, they click OK on the prompt and are presented with another browser window (screen shot attached). The error returned is as follows:
An error occurred during OAuth2 operation. Please contact your administrator to resolve the issue.
{ "error": "invalid_request","error_description": "Invalid client" }
The user is never presented with the VRA Login page.
We currently have the VRA_VIDM rule selected as inactive due to this issue. It appears as though ServiceNow is importing the VRA content, no errors from any of the Scheduled Import jobs aside from the occasional "no sensors defined" error.
