Consult the online documentation for Services for UNIX for more information on
configuring User Name Mapping. To view the online documentation for Services for
UNIX on the Model 326 (either node can be used):
1. From the Model 326 desktop, click the IBM NAS Admin icon.
2. On the left pane of the IBM NAS Admin console, expand File Systems .
3. Expand Services for UNIX .
4. Select any of the items that appear under Services for UNIX .
5. Click anywhere on the right pane of the IBM NAS Admin console, then press
the F1 key to bring up the online documentation for Services for UNIX in a
separate window.
Configuring Server for NFS
This section describes how to configure Server for NFS.
Services for UNIX is installed on every IBM NAS machine. Additional installation is
required only when the NAS is installed into a Windows domain. If the NAS is
installed as part of a Windows 2000 domain, you must install the Server for NFS
Authentication module on the domain controllers. This module is on the
Supplementary CD.
User and group identification
You can enumerate UNIX users and groups by using one of two methods: get the
data from an NIS server, or from local copies of the UNIX
passwd and group files. If
you use an NIS server, no special preparation is necessary. If local files are used,
you must copy them to the NAS machine and possibly modify their format for use
by the User Name Mapping function, as described in “Preparing local copies of
passwd and group ”.
Preparing local copies of passwd and group : If you will be using an NIS server,
go to “Creating Windows users and groups” on page 74. If you are using local files
instead of NIS, you must import these files to the NAS and prepare them as follows.
Obtain copies of the UNIX passwd and group files. Copy them into directories on
the NAS machine as:
c:\winnt\system32\drivers\etc\passwd
and
c:\winnt\system32\drivers\etc\group
Next, delete all special users and groups, leaving just the actual users and groups
that will be used in accessing files. An example of a special user is
root , usually,
and UID numbers from 0 to 99 are generally reserved for system accounts and
should not be mapped.
Services for UNIX supports a limited syntax in the passwd file. In particular, it
seems to work best when the second field of each line — the password field — is
filled in with a random 13-character string. This need not have anything to do with
the user’s password, so a string such as
0123456789012 is acceptable. Some
UNIX systems use shadow passwords and fill in this field with a meaningless token
value such as
x or ! , and you will need to change this.
Finally, if this is a clustered NAS, copy these finished files to the same location on
the other node. Both nodes must have the same files for the system to failover
properly.
