NAME

       bos_setauth - Sets authorization checking requirements for all server processes

SYNOPSIS

       bos setauth -server <machine name> -authrequired (on | off)
           [-cell <cell name>] [-noauth] [-localauth] [-help]

       bos seta -s <machine name> -a (on | off)
           [-c <cell name>] [-n] [-l] [-h]

DESCRIPTION

       The bos setauth command enables or disables authorization checking on the server machine named by the
       -server argument. When authorization checking is enabled (the normal case), the AFS server processes
       running on the machine verify that the issuer of a command meets its privilege requirements. When
       authorization checking is disabled, server processes perform any action for anyone, including the
       unprivileged user "anonymous"; this security exposure precludes disabling of authorization checking
       except during installation or emergencies.

       To indicate to the server processes that authorization checking is disabled, the BOS Server creates the
       zero-length file /var/lib/openafs/local/NoAuth on its local disk. All AFS server processes constantly
       monitor for the NoAuth file's presence and do not check for authorization when it is present. The BOS
       Server removes the file when this command is used to re-enable authorization checking.

CAUTIONS

       Do not create the NoAuth file directly, except when directed by instructions for dealing with emergencies
       (doing so requires being logged in as the local superuser "root"). Use this command instead.

OPTIONS

       -server <machine name>
           Indicates  the  server  machine  on  which  to enable or disable authorization checking. Identify the
           machine by IP address or its host name (either fully-qualified  or  abbreviated  unambiguously).  For
           details, see bos(8).

       -authrequired (on | off)
           Enables authorization checking if the value is "on", or disables it if the value is "off".

       -cell <cell name>
           Names  the  cell  in which to run the command. Do not combine this argument with the -localauth flag.
           For more details, see bos(8).

       -noauth
           Assigns the unprivileged identity "anonymous" to the issuer.  Do  not  combine  this  flag  with  the
           -localauth flag. For more details, see bos(8).

       -localauth
           Constructs  a  server  ticket  using  a  key from the local /etc/openafs/server/KeyFile file. The bos
           command interpreter presents the ticket to the  BOS  Server  during  mutual  authentication.  Do  not
           combine this flag with the -cell or -noauth options. For more details, see bos(8).

       -help
           Prints the online help for this command. All other valid options are ignored.

EXAMPLES

       The following example disables authorization checking on the machine "fs7.abc.com":

          % bos setauth -server fs7.abc.com -authrequired off

PRIVILEGE REQUIRED

       The  issuer  must  be listed in the /etc/openafs/server/UserList file on the machine named by the -server
       argument, or must be logged onto a server machine as the local superuser "root" if the -localauth flag is
       included.
