# ServiceName

DEPRECATED: The `ServiceName` parameter is deprecated for Controller version 12.6.0 and later.

You can use GSS authorization without using ACI encryption by configuring the GSSServiceName and RequireGSSAuth parameters.

The `ServiceName` parameter is still available for existing implementations, but it might be incompatible with new functionality. The parameter might be deleted in future.

The name of Kerberos principal. If this Controller is part of a system using the Kerberos authentication protocol, this parameter gives the Kerberos principal name assigned to this Controller.

The Kerberos principal name consists of:

- the Kerberos service name (for example, `IDOL/`).

- the instance name (the fully qualified host name; for example, `myserver.acme.com`)

- the Kerberos realm (normally the domain name in uppercase; for example, `@ACME.COM`).

NOTE: To use Kerberos, you must also set CommsEncryptionType to `GSS`.
