Managing protocol user authentication
The system administrator can configure authentication for both object and file access either during the installation of the system or after the installation. If the authentication configuration is not configured during installation, you do it manually by using the mmuserauth service create command from any node in the IBM Storage Scale cluster. You can use the manual method of configuring authentication for the file and object access.
Client system authentication requirement: When you use GPFS clients or the NFS or SMB protocol to access
the files in an IBM Storage Scale file system, the
authentication and ID mapping of users and groups must be configured on the client operating system
on which the file system or share is mounted. You must configure the appropriate directory services
(AD, LDAP, or NIS) on that operating system, and users and groups must be able to log in with their
user IDs and group IDs. User IDs and group IDs are the actual credentials that the file
system uses to authenticate users and groups who try to access the file system through
the GPFS clients.
