The user (for the tenant) must exist on all the cluster nodes with the
same UID and GID or all the cluster nodes must connect to the same LDAP
server. See
Managing Users and Groups for more information.
NOTE: The superuser for a tenant, referred to as tenant admin,
must have a UID of 0
on the tenant host(s) to
access the tenant volume (only) and all data in the tenant volume.
Although the tenant admin has the same UID as the MapR superuser,
the tenant admin does not have the same level of access and
administration privileges as the MapR superuser because the tenant
admin’s access is based on the tenant ticket and is restricted to
the tenant volume.
