bos_adduser - Adds a privileged user to the UserListExt file


bos adduser -server <machine name> -user <user names>+ -type <user type: superuser|reader> [-rxkad] [-cell <cell name>] [-noauth] [-localauth] [-principal <authentication principal> [-encrypt [<yes|no>]] [-verbose] [-config <configuration file>] [-help]


The bos adduser command adds each user name specified with the -user argument to the /etc/yfs/server/UserListExt file on the machine named by the -server argument. It is the issuer's responsibility to verify that an entry for the user exists in the Protection database and the Kerberos 5 database(s) for the realm(s) listed in the /etc/yfs/server/krb.conf file.


-server <machine name>

Indicates the server machine on which to change the /etc/yfs/server/UserListExt file. Identify the machine by IP address or its host name (either fully-qualified or abbreviated unambiguously). For details, see bos(8).

In cells that use the Update Server to distribute the contents of the /etc/yfs/server directory, it is conventional to specify only the system control machine as a value for the -server argument. Otherwise, repeat the command for each file server machine. For further discussion, see bos(8).

-user <user names>+

Specifies each user name to insert into the /etc/yfs/server/UserListExt file.


Indicates that the specified user names are rxkad names.

-type superuser|reader

Indicates the type of user to be added. Users are added to the /etc/yfs/server/UserListExt file if the superuser type is specified or if this option is not present. If the type is reader the users are added to the /etc/yfs/server/ReaderList file. Users on the /etc/yfs/server/ReaderList are allowed to perform many query operations but are not allowed to perform operations that modify the configuration.

-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).


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


Constructs a server ticket using a key from the local /etc/yfs/server/KeyFileExt 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).

-principal <authentication principal>

Indicates the principal to be used for authentication. This option can be useful when several credentials caches are available for different principals.

-encrypt [<yes|no>]

Enables or disables encryption for the command so that the operation's results are not transmitted across the network in clear text.


Produces on the standard output stream a detailed trace of the command's execution. If this argument is omitted, only warnings and error messages appear.

-config <configuration file>

Sets the location of the configuration file to be used. The default file is /etc/yfs/yfs-client.conf.


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


The following command adds the user names pat and smith to the /etc/yfs/server/UserListExt file on the machine (the system control machine).

   % bos adduser -server -user pat smith


The issuer must be listed in the /etc/yfs/server/UserListExt file on the machine named by the -server argument, or must be logged onto a server with an account capable of reading the /etc/yfs/server/KeyFileExt file if the -localauth flag is included.
