=head1 NAME

NoAuth - Disables authorization checking

=head1 DESCRIPTION

The F<NoAuth> file, if present in a server machine's F</usr/afs/local>
directory, indicates to the AFS server processes running on the machine
that it is not necessary to perform authorization checking. They perform
any action for any user who logs into the machine's local file system or
issues a remote command that affects the machine's AFS server functioning,
such as commands from the AFS command suites. Because failure to check
authorization exposes the machine's AFS server functionality to attack,
there are normally only two circumstances in which the file is present:

=over 4

=item *

During installation of the machine, as instructed in the I<OpenAFS Quick
Start Guide>.

=item *

During correction of a server encryption key emergency, as discussed in
the I<OpenAFS Administration Guide>.

=back

In all other circumstances, the absence of the file means that the AFS
server processes perform authorization checking, verifying that the issuer
of a command has the required privilege.

Create the file in one of the following ways:

=over 4

=item *

By issuing the bosserver initialization command with the B<-noauth> flag,
if the Basic OverSeer (BOS) Server is not already running.

=item *

By issuing the B<bos setauth> command with off as the value for the
B<-authrequired> argument, if the BOS Server is already running.

=back

To remove the file, issue the B<bos setauth> command with C<on> as the
value for the B<-authrequired> argument.

The file's contents, if any, are ignored; an empty (zero-length) file is
effective.
