Using null sessions to access storage in non-Kerberos environments

Null session access provides permissions for network resources, such as storage system data, and to client-based services running under the local system. A null session occurs when a client process uses the system account to access a network resource. Null session configuration is specific to non-Kerberos authentication.

  • How the storage system provides null session access
    Because null session shares do not require authentication, clients that require null session access must have their IP addresses mapped on the storage system.
  • Granting null users access to file system shares
    You can allow access to your storage system resources by null session clients by assigning a group to be used by null session clients and recording the IP addresses of null session clients to add to the storage system’s list of clients allowed to access data using null sessions.
