There are several reasons for creating local users and groups on your Storage Virtual Machine (SVM). For example, you can access the CIFS server using a local user account if the domain controllers are unavailable, or you may want to use local groups to assign privileges.
You can create one or more local user accounts for the following reasons:
Local users can authenticate with the CIFS server using NTLM authentication when the domain controller is down or when network problems prevent your CIFS server from contacting the domain controller.
User Rights Management is the ability for a CIFS server administrator to control what rights users and groups have on the SVM. You can assign privileges to a user by assigning the privileges to the user's account or by making the user a member of a local group that has those privileges.
You might want to create one or more local groups for the following reasons:
There are certain built-in user groups with predefined privileges. To assign a customized set of privileges, you can create a local group and assign that group the necessary privileges. You can then add local users, domain users, and domain groups to the local group.
