You can use local users for authentication,
1. Create Local Admin User
useradmin user add test -g Administrators
2. Access the CIFS share
You can now attempt to access the c$ or etc$ shares via SMB using a client machine. For example, if you're on a Windows machine, follow these steps:
2.1Map Network Drive:
Open File Explorer on your Windows machine.
In the address bar, type:
\\<NetApp_IP>\c$
\\<NetApp_IP>\etc$
Replace <NetApp_IP> with the actual IP address of the 7-mode system.
2.2Authentication:
When prompted for credentials, enter the local admin user credentials you verified or created earlier
