   Table 1 Basic user mapping parameters

   Parameter	Description
   Mapping Mode	Kerberos to UNIX: When accessing UNIX shares using Kerberos authentication through a client, a Kerberos user has all the permission granted to the target user.
   Source User	Source user in the mapping. The source user must be an uppercase client host name. If KDC Vendor is set to Windows, add $ as the suffix. Example, HOSTNAME$. If KDC Vendor is set to Non-Windows, add the domain name as the suffix. Example, HOSTNAME.example.com, where HOSTNAME is the uppercase client host name. Wildcard character * is supported. For example, * indicates all client hosts, and CLIENT* indicates hosts whose names start with CLINET. NOTE: In the scenario of accessing the audit log namespace, the source user cannot be the same as the local UNIX authentication user under the same account.
   Target User	Target user in the mapping. The target user can be: A local UNIX user on the storage system: Map the permissions of the source users to the local UNIX user on the storage system. If there is no local UNIX user, create one. An LDAP or NIS domain user: Map the permissions of the source users to the LDAP or NIS domain user. Set this parameter based on the permission requirements of the target user. NOTE: To access the audit log namespace, the target user must be a local UNIX authentication user whose ID is 0 with the root permission under the same account.
   Priority	Priority of the mapping. A smaller value indicates a higher priority. When multiple mappings share the same source user, the system uses the mapping with the highest priority. [Value range] 1 to 32

5. Click Add to Mapping List to add the mapping to the list below.
