Estimados, buenas tardes, estoy desarrollando un sitio con MVC 5 y quiero agregarle el Login a un Active Directory. Podrian facilitarme algo de información de los puntos a tener en cuenta, tiene presente que el sitio ya esta funcionando, sin ningún tipo de seguridad. La información seria con relación al agregado de las pantallas, cambios en el codigo y configuración del web.config. Ya que entre los cambios que ya intente me aparecen varios errores que no me dejan avanzar uno, por ejemplo es el siguiente: HTTP Error 404.15 - Not FoundThe request filtering module is configured to deny a request where the query string is too long. Most likely causes:Request filtering is configured on the Web server to deny the request because the query string is too long. Things you can try:Verify the configuration/system.webServer/security/requestFiltering/requestLimits@maxQueryString setting in the applicationhost.config or web.config file.

Do not change this feature unless the scope of the change is fully understood. You can configure the IIS server to reject requests whose query string is greater than a specified value. If the request's query string is greater than the configured value, this error is returned. If the allowed length of the query string needs to be increased, modify the configuration/system.webServer/security/requestFiltering/requestLimits@maxQueryString setting.View more information » Muy Cordialmente.
