112 Chapter 4 Managing Clients and Users
Mapping Windows User and Group IDs
You can use the Windows ID Mapping setting for a volume to specify how Windows
clients map user and group information to Xsan-compatible user IDs (UIDs) and group
IDs (GIDs), which they need in order to access Xsan volumes.
Note: To use ID mapping, Windows clients must be running StorNext 2.7. Xsan
controllers and clients must be running Xsan 1.3 or later.
Windows clients can use either of these methods to provide UIDs and GIDs:
 Generate IDs from GUID: Windows clients dynamically generate UIDs and GIDs
based on Globally Unique Identifier (GUID) information in an Active Directory
domain. This is the method you should choose if, for example, Macintosh computers
on the SAN are bound to Active Directory and the Directory Access Active Directory
plug-in is set to automatically generate IDs.
 Use IDs from LDAP (RFC 2307): Windows clients get UID and GID values from the
uidNumber and gidNumber attributes in Active Directory records. Choose this
method if, for example, Macintosh computers on the SAN are bound to Active
Directory and the Directory Access Active Directory plug-in is set to map IDs to
uidNumber and gidNumber.
Important: To avoid ID conflicts, be sure all computers on the SAN use the same Active
Directory domain and the same method of ID mapping.
