How name mapping works

Data ONTAP goes through a number of steps when attempting to map user names. They include checking the local name mapping database and LDAP, trying the user name, and using the default user if configured.

When Data ONTAP has to map credentials for a user, it first checks the local name mapping database and LDAP server for an existing mapping. Whether it checks one or both and in which order is determined by the name service configuration of the Storage Virtual Machine (SVM).
