    Specifies a node name. If you specify an asterisk wildcard
    character (*),  the specified remote user on all nodes is served
    by the local user.

 remote-user

    Specifies the user name of a user at a remote node. If you
    specify an asterisk wildcard character, all users at the
    specified node are served by the local user.

    asterisk wildcard in the group and member fields of the UIC.
