I have configured FBA in SharePoint 2013 as per below URL.


When i try to login SharePoint portal with FBA user i am getting below Error message in SharePoint Screen.

The server could not sign you in. Make sure your user name and password are correct, and then try again.

If i look at my event viewer log i am getting below error message.

An exception occurred when trying to issue security token: The security token username and password could not be validated..

Any help would be greatly appreciated.
