Local user-based authentication
You must configure SMB users on the corresponding storage server and enter the credentials on the client.
If the SMB service is part of a Windows domain, the Windows domain users can use the SMB share. In this scenario, credentials are not required to access the share.
For Azure Kubernetes Service (AKS) and Amazon Elastic Kubernetes Service (EKS) cloud platforms, only a SMB local user can access the SMB share. You must add SMB users to access the SMB share.
If the SMB service is not part of Windows domain, perform the following steps:
For a NetBackup Appliance:
For a NetBackup Appliance, local users are also SMB users. To manage local users, log in to the CLISH and select . The SMB password is the same as the local user's login password.
For an MDSP BYO server:
For an MDSP BYO server, create a Linux user (if one does not exist). Then, add the user to SMB.
For example, the following commands create a test_smb_user use for the SMB service only:
# adduser --no-create-home -s /sbin/nologin test_smb_user
# smbpasswd -a test_smb_user
To add an existing user to the SMB service, run the following command:
# smbpasswd -a username
For a Flex Appliance primary or media server application instance:
For a Flex Appliance primary or media server application instance, log in to the instance and add any local user to the SMB service as follows:
If desired, create a new local user with the following commands:
#useradd <username> #passwd <username>
You can also use an existing local user.
Run the following commands to create user credentials for the SMB service and enable the user:
smbpasswd -a <username> smbpasswd -e <username>
For a WORM storage server application instance:
For a WORM storage server instance, log in to the instance and add a local SMB user with the following command: setting smb add-user username=<username> password=<password>
You can view the new user with the setting smb list-users command. To remove a user, run the setting smb remove-user username=<username> command.
For the AKS and the EKS cloud platform:
Log in to the MSDP engine pod in a cluster using kubectl.
Run the following command to log in to RShell in the MSDP engine.
su - msdpadm
Run the following RShell command to add a SMB user.
setting smb add-user username=[samba user name]
For example,
msdp-16.1] > setting smb add-user username=test_samba_user
You can use the same command to update the password for an existing user.
In AKS and EKS cloud platforms, the SMB RShell command configures SMB servers in all MSDP engines in a cluster.
