Dell EMC SmartFabric OS10 User Guide Release 10.5.0

Unknown user role

When a RADIUS or TACACS+ server authenticates a user, it may return an unknown user role, or the role may be missing. In these cases, OS10 assigns the netoperator role and associated permissions to the user by default. You can reconfigure the default assigned role. In addition, you can configure an unknown RADIUS or TACACS+ user-role name to inherit the permissions of an existing OS10 system-defined role.

• Reconfigure the default OS10 user role in CONFIGURATION mode.

  userrole {default | name} inherit existing-role-name

  • default inherit — Reconfigure the default permissions assigned to an authenticated user with a missing or unknown role.
  • name inherit — Enter the name of the RADIUS or TACACS+ user role that inherits permissions from an OS10 user role; 32 characters maximum.
  • existing-role-name — Assign the permissions associated with an existing OS10 user role:
    • sysadmin — Full access to all commands in the system, exclusive access to commands that manipulate the file system, and access to the system shell. A system administrator can create user IDs and user roles.
    • secadmin — Full access to configuration commands that set security policy and system access, such as password strength, AAA authorization, and cryptographic keys. A security administrator can display security information, such as cryptographic keys, login statistics, and log information.
    • netadmin — Full access to configuration commands that manage traffic flowing through the switch, such as routes, interfaces, and ACLs. A network administrator cannot access configuration commands for security features or view security information.
    • netoperator — Access to EXEC mode to view the current configuration with limited access. A network operator cannot modify any configuration setting on a switch.
