Cause

La configuración predeterminada de monitoring-app.properties para el tamaño del encabezado HTTP es 8 KB. Es posible que el encabezado HTTP predeterminado no sea suficiente para dar cabida a todos los encabezados con una configuración grande de usuario o grupo de Active Directory.

Resolution

Aumente la configuración del tamaño del encabezado HTTP monitoring-app.properties en NetWorker Server.

  • Agregue una nueva línea para el server.max-http-header-size opción con valor de 32 KB
server.max-http-header-size=32KB
  • Guarde los cambios en el archivo monitoring-app.properties de NetWorker.
