How to maintain the client credentials to a report server and maintain these credentials until it reaches a SQL server

Error al representar el cliente. Error al procesar el informe. (rsProcessingAborted) No se puede crear una conexión al origen de datos 'CN_DesarrolloRegional'. (rsErrorOpeningConnection) Error de inicio de sesión del usuario 'NT AUTHORITY\ANONYMOUS LOGON'.

Sorry, my server is in Spanish, but basically what it states is that there is an error authenticating the client because the report server is trying to access to a SQL Server with an 'ANONYMOUS LOGON' .. it is possible to authenticate to this last server with my initial credential from the client?

I found this article but I don't understand it completely http://blogs.msdn.com/b/psssql/archive/2010/06/23/my-kerberos-checklist开发者_开发知识库.aspx

You need to use kerberos as the article states. If you can't do that, then you'll have to have the user enter credentials or store some reporting credentials on the server (a sql login).

Perhaps you can ask for clarifications on what you don't comprende.
