I'm trying to configure FBA on sharepoint 2013 foundation. Followed each steps described in technet. Still getting error "
An exception occurred when trying to issue security token: The server was unable to process the request due to an internal error. For more information about the error, either turn on IncludeExceptionDetailInFaults (either from ServiceBehaviorAttribute or from the configuration behavior) on the server in order to send the exception information back to the client, or turn on tracing as per the Microsoft .NET Framework SDK documentation and inspect the server trace logs..
May be in past i have seen some comments regarding this from your side but now not able to get it. Kindly help.
