## pts adduser

Purpose

Adds a user or machine to a Protection Database group

Synopsis

    pts adduser -user <user name>+  -group <group name>+
                [-cell <cell name>]  [-noauth]  [-force]  [-help]

    pts ad -u <user name>+  -g <group name>+  [-c <cell name>]  [-n]  [-f]  [-h]

Description

The pts adduser command adds each user or machine entry named by the -user argument as a member of each group named by the -group argument.

To remove members of a group, use the pts removeuser command. To list the groups to which a user or machine belongs, or the members of a specified group, use the pts membership command.

Cautions

After being added as a group member, a currently authenticated user must reauthenticate (for example, by issuing the klog command) to obtain permissions granted to the group on an access control list (ACL).

Options

-user
  Specifies the name of each user or machine entry to add to each group named by the -group argument. The name of a machine entry resembles an IP address and can use the wildcard notation described on the pts createuser reference page. The user or machine entry must already exist in the Protection Database.

-group
  Specifies the complete name (including the owner prefix if applicable) of each group to which to add members. The group entry must already exist in the Protection Database.

-cell
  Names the cell in which to run the command. For more details, see the introductory pts reference page.

-noauth
  Assigns the unprivileged identity anonymous to the issuer. For more details, see the introductory pts reference page.

-force
  Enables the command to continue executing as far as possible when errors or other problems occur, rather than halting execution at the first error.

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

Examples

The following example adds user smith to the group system:administrators.

       % pts adduser -user smith -group system:administrators

The following example adds users jones, terry, and pat to the smith:colleagues group.

       % pts adduser -user jones terry pat -group smith:colleagues

The following example adds the machine entries in the ABC Corporation subnet to the group bin-prot. Because of the IP address range of the ABC Corporation subnet, the system administrator was able to group the machines into three machine entries (using the wildcard notation discussed on the pts createuser reference page).

       % pts adduser -user 138.255.0.0 192.12.105.0 192.12.106.0 -group bin-prot

Privilege Required

The required privilege depends on the setting of the fourth privacy flag in the Protection Database entry for each group named by the -group argument (use the pts examine command to display the flags):

- If it is the hyphen, only the group's owner and members of the system:administrators group can add members.

- If it is lowercase `a`, current members of the group can add new members.

- If it is uppercase `A`, anyone who can access the cell's database server machines can add new members.
