# System Admin Configuration Types

System Admin configurations set values for system administrative settings. The available System Admin configuration types are listed here.

## Authentication External

An Authentication External configuration defines values and behavior for a hardware or software system requiring authentication to an external server, such as LDAP or RADIUS.

After changing the Authentication Method on a host, you must delete the host from ArcMC, then re-add it using Node Management.

Note: Authentication External configurations can only be imported from managed Loggers, not created in ArcMC. See Importing a Subscriber Configuration for more information.
