NIS Domain
Chapter 3 User & Group Management 27
Directory domains as member servers. References to the Snap Server's shares can be
added to organizational units (OU) as shared folder objects.
Guest Account Access to the Snap Server
The
Security > Windows
screen contains an option that allows unknown users to
access the Snap Server using the guest account.
Restrict_Anonymous and PDC Access
If you have implemented the restrict_anonymous mechanism on your network, you
may need to enter a valid domain (not local) user name and password that the Snap
Server can use to communicate with the PDC. For ease of administration, Snap
Appliance recommends that you create a unique user account on the domain using
the following guidelines: (1) choose a name, such as
SnapServerAccess , and include a
comment that makes the function of the account clear; and (2) set the password to
never expire.
NIS Domain
NIS domains are configured on the
Security > NIS
screen of the Administration Tool.
The Snap Server can join an NIS domain and function as an NIS client. It can then
read the users and groups maintained by the NIS domain. Thus, you must use the
NIS server to make modifications. Changes you make on the NIS server do not
immediately appear on the Snap Server; it may take up to 10 minutes for changes to
be replicated.
Guidelines for Configuring NIS
Consider the following when configuring NIS access.
Handling UID/GID Assignments
Unless UID/GID assignments are properly handled, NIS users and groups may fail
to display properly. For guidelines on integrating compatible Snap Server UIDs, see
“UID and GID Assignments” on page 23.
Tip
NIS identifies users by UID, not user name, and although it is possible to have
duplicate user names, Snap Appliance does not support this configuration.
