Synchronizing Active Directory 2008 with the NTP server used by the cluster
It is important to synchronize Active Directory with the NTP server used by the StoreAll cluster. Run
the following commands on the PDC:
net stop w32time
w32tm /config /syncfromflags:manual /manualpeerlist:""
w32tm /config /reliable:yes
net start w32time
To check the configuration, run the following command:
w32tm /query /configuration
HP-SMB user name mapping
With HP-SMB username mapping, you can create an enterprise-wide single login (username and
password) for local or cluster-wide administration of cluster file system resources. Such mapping
can be especially useful to manage cross-protocol file system authorization compatibility where
Linux user names are not the same as SMB/CIFS user names. SMB/CIFS user names often contain
pre-appended domain names and are case insensitive, while Linux user names do not generally
contain a pre-appended domain name and are case sensitive. By implementing HP-SMB username
mapping, you can avoid the need to change ownership of permissions or ACLs on existing file
systems objects when a user has different SMB/CIFS and Linux user names and the user requires
access to files independent of the access protocol. Another reason for using the HP-SMB username
mapping is provide multiple user access to SMB/CIFS shares and files without having to keep a
password known and used by multiple users.
The following list provides an overview of the features provided by HP-SMB username mapping:
•
Allows users of HP-SMB file servers to map CIFS users to users of native Linux name services
•
Mapped user inherit UID, primary group, and supplemental memberships of the Linux user
