maps.
2. Specify the Windows Domain. If the server is configured as PCNFS, go to step 4.
3. Click List UNIX Users or List UNIX Groups.
This action refreshes your UNIX users or groups selection.
4. Create map entries by selecting a Windows user or group and a UNIX user (UID) or group (GID) from the list and clicking Add.
5. Click OK to create the maps.
Basic Scenarios
For UNIX and Windows NT User Name Mapping, an NIS Server must already exist in the UNIX environment, or UNIX user and group files must exist on the
PowerVault NAS system. User Name Mapping associates UNIX users and groups to Windows NT users and groups. You can use two types of maps, simple and
explicit. Simple maps define a one-to-one relationship between the same user names and groups. Explicit maps define a relationship between dissimilar user
names and groups.
Workgroup
In the workgroup scenario, you configure User Name Mapping locally on the NAS system. All maps are contained on this system.
Domain
In the domain scenario, you configure NFS Authentication on all domain controllers. The NT Authentication Service installation program must be installed on the
domain controller and available in the DomainUtils share on the NAS system.
To install the NT Authentication Service on a domain controller, perform the following steps:
1. Log in to the domain controller as an administrator.
2. Map the NAS system's DomainUtils share.
3. Run sfucustom.msi, which is located in the Services for Unix directory.
Filename Character Translation
Although Windows and UNIX file systems do not allow certain characters in filenames, the characters that are prohibited by each operating system are not the
same. For example, a valid Windows filename can not contain a colon (:), but a UNIX filename can. If a UNIX user attempts to create a file in an NFS share and
that file contains an illegal character in its name, the attempt will fail.
You can use filename character translation to replace characters that are not allowed in a file system by mapping them to characters that are valid. To enable
filename character translation, create a text file that maps Windows to UNIX characters, and then modify the registry entry that specifies the path and name of
the translation file.
The filename character translation text file is a list of mapped characters in the following format, such as the following:
0xnn : 0xnn [ ; comment ]
where nn is the hexadecimal value of the character
The entry for a map from the UNIX character ":" to the Windows character "-" in the filename character translation text is as follows:
