      The root cause of login module failures gets lost when multiple login modules are stacked and the "flag" attribute is set to "optional".

      When the login attempt fails (invalid bindCredential on the AdvancedLdapLoginModule for example) the authentication request will continue to the next login module in the stack. In this situation, the exceptions "cause" attribute is getting overwritten during the processing of the other login modules. This results in the actual cause to get lost during processing.

      This makes troubleshooting authentication failures difficult.
