   Table 1. NAS server user mappingsColumn one lists the tasks, column two describes how to perform each task.

   Task	Description
   Map together UNIX accounts and Windows accounts that have different usernames.	The ntxmap configuration file lets you map together UNIX accounts and Windows accounts that have different usernames. The syntax for ntxmap is displayed in the template that you retrieve by following these steps: Select Local Files. On the local files list, select the download icon next to Ntxmap to retrieve it. NOTE:If there is no custom mapping file, the NAS server retrieves a template for configuration. Use a text editor to add or change user account mappings in the file. Select Upload Local Files and then select ntxmap from the File Type options. Use the browser to select the updated file and select Upload.
   Automatically generate a UNIX UID for each Windows user that is not mapped to a UNIX account.	Select User Mapping. Select Enable automatic mappping for unmapped Windows accounts/users. This option is for multiprotocol environments in which most users are Windows users. When you select this option, the system generates UNIX UIDs for Windows users that are not already mapped to UNIX accounts through a directory service (LDAP or NIS) or local files. This functionality allows for the retention of file system quotas for unmapped Windows users.
   Enable or disable default accounts for unmapped users.	Select User Mapping. Select or clear the Enable default account for unmapped users option. If you enabled this option, set the default UNIX user (name or UID/GID) and the default Windows username. If you enable default accounts for unmapped users, you can enter default UNIX and Windows accounts that the system uses to grant file system access to unmapped users. The default UNIX user can be a valid existing UNIX account name or follow the format @uid=xxxx,gid=yyyy@, where xxxx and yyyy are the decimal numerical values of the UID and the primary GID, respectively. NOTE:If you are using default accounts, the users are mapped to one UID, and only one user quota applies to all users.
