Use the XAUTH -f ADD command to manually create an X authority
    file. You must manually create an X authority file for the
    server when enabling authentication outside of a DECwindows
    Motif session. You can also choose to create additional user X
    authority files to store alternate authentication settings, such
    as for authorizing untrusted network connections.

    An X authority file name can consist of any characters currently
    supported by OpenVMS; however, the file extension is restricted
    to a maximum of 37 characters and version numbers are not
    allowed.

    The -f option specifies the name of the X authority file, and
    the ADD command creates the file by adding an entry. If you do
    not enter a fully-qualified filename, the new X authority file is
    written to the current directory by default.

    For example, the following command creates a new X authority file
    UNTRUSTED.DECW$XAUTH to be used to authorize untrusted network
    connections:

    $ XAUTH -f UNTRUSTED.DECW$XAUTH ADD :0 .
