noauth

NOAUTH(5)							AFS File Reference							 NOAUTH(5)

NAME
       NoAuth - Disables authorization checking

DESCRIPTION
       The NoAuth file, if present in a server machine's /var/lib/openafs/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:

       o   During installation of the machine, as instructed in the OpenAFS Quick Start Guide.

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

       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:

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

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

       To remove the file, issue the bos setauth command with "on" as the value for the -authrequired argument.

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