Access to XMLHTTPRequest has been blocked by CORS policy

Follow

SecureAuth version affected: All

Description:

Access to XMLHTTPRequest has been blocked by CORS policy. Request Header Field tokenid is not allowed by Access-Control-Allow-Headers

 

Cause:

HTTP Response Headers in IIS are restricting  this.

 

Resolution:

Check that the Field mentioned in the error above (In my example, tokenid) is a header that you wish to allow. If so, edit the Response Headers to allow it. 

1. Open IIS
2. Navigate to the realm
3. Double click on the HTTP Response Headers option
4. Add

In my example, I am specifically setting tokenid
