dce-authentication

If you define this attribute, the specified file service uses DCE security rather than the native UNIX password security, such as NIS. If you define a different authentication method--for example, if you set the client-encryption or share-mode attribute to on, or if you define authent-proxy--it takes precedence over DCE security. This attribute only works when you install the TAS-DCE package. This attribute does not control the acquisition of DCE credentials. DCE-enabled host systems always acquire appropriate DCE credentials, if possible.

Usage:

tnservice -M -r realm -s service -a dce-authentication={on|off}
