Creating And Managing User And Group Mappings - HP ProLiant 300 Series Administration Manual

• Back up user and group mappings
To avoid loss of complex advanced mappings in the case of a system failure, back up the
mappings whenever the mappings have been edited or new mappings have been added.
• Map consistently
Groups that are mapped to each other should contain the same users, and members of the groups
should be properly mapped to each other to ensure proper file access.
Example using User1 and Group1:
• Verify that the Windows User1 is mapped to the corresponding UNIX User1.
• Verify that the Windows Group1 is mapped to the corresponding UNIX Group1.
• Verify that User1 is a member of Group1 on both Windows and UNIX.
• Map properly
• PCDATA cannot be inserted: Valid UNIX users should be mapped to valid Windows users.
• PCDATA cannot be inserted: Valid UNIX groups should be mapped to valid Windows groups.
• PCDATA cannot be inserted: The mapped Windows user must have the "Access this computer
from the Network privilege," or the mapping will be squashed.
• PCDATA cannot be inserted: The mapped Windows user must have an active password,
or the mapping will be squashed.

Creating and managing user and group mappings

NOTE:
The following sections are for a stand alone configuration. In a clustered environment, clicking User and
Group Mappings displays a log in screen for the Services for NFS Administrator.
To set up and manage user name mappings:
1. From the WebUI, click Shares, Sharing Protocols. Click NFS Protocol, and then click
Properties.
The NFS Properties page is displayed.
2. In the NFS Properties page, click User and Group Mappings.
There are four tabs in the User and Group Mappings page:
• General information—Sets the mapping information source, which is either NIS or
password and group files.
• Simple Mapping—Indicates whether simple mappings are being used.
• Explicit User Mapping—Lists exceptional user mappings that will override the simple
user mappings.
• Explicit Group Mapping—Lists exceptional group mappings that will override the
simple group mappings.
Each of these tabs is discussed in the following sections.
3. Enter mapping information on the appropriate tabs, and then click OK.
