You can add users manually or retrieve users and set them to be 'local' users. The typical use of this feature is to allow access to the cluster on an exceptional basis to a user who is not known to your auth provider.
When a local user requests access to a resource on the cluster, the cluster authorizes access (or not) based on the attributes in the user's local entry without updating the user entry from the auth provider.
Local users are supported only when accessing the cluster via NFS.
Using this procedure you can either add a completely new user to the UDB and define it as a local user or you can retrieve an existing user from the UDB, using the UID. You can set that existing user to be local and edit the user's attributes.
From the left navigation menu, select User Management and then Users.
Click Create User and complete the following fields:
A unique name for the user.
The user's UID. Note that if you enter a UID that already belongs to another user entry, you won't be able to create a parallel entry and assign the user's remaining attributes (GIDs etc). They will be updated from the existing entry after you click Create.
The user's leading GID (otherwise known as primary GID). The VAST file system will by default assign the user's primary GID as the owning group of any files created by the user.
Group IDs of all other groups that the user belongs to beside the primary group.
Leave this field enabled (as per default). This setting defines the user as local and does not need to be renewed from your auth provider (LDAP, NIS).
In the event that there is an existing user entry in the VAST Cluster user database with the same UID, the pre existing user entry from the user database is retrieved and displayed.
If you need to modify a user that you created or retrieved from the UDB (by specifying its UID), click to open the Actions menu for the user and select Edit. Make the changes you need in the Update User dialog and click Update.
See user add to add a user.
