# GSSServiceName

The GSSAPI service name that you want to use for the Slack Connector service. You must specify the GSSAPI service name, instance name (fully qualified host name), and the Kerberos realm (normally the domain name in upper case).

You can also set `GSSServiceName` to an asterisk (`*`) to allow clients to authenticate to any service principal in the Slack Connector service's keytab, rather than requiring you to select a single principal.

If you enable GSSAPI authentication, Slack Connector uses this value as the GSSAPI service name to identify itself. You enable GSSAPI authentication by setting the `RequireGSSAuth` parameter in the appropriate section:

- ACI port: `[Server]` RequireGSSAuth
- Service port: `[Service]` RequireGSSAuth

NOTE: You cannot use `RequireGSSAuth` with GSS ACI encryption (see ACI Encryption Configuration Parameters). If you configure both, Slack Connector does not start. GSS ACI encryption has been deprecated or Slack Connector version 12.6.0 and later.
