ROLEADD(8) Maintenance Commands and Procedures ROLEADD(8)

NAME

roleadd - administer a new role account on the system

SYNOPSIS

roleadd [-A authorization[,authorization]...]
[-b base_dir] [-c comment] [-d dir] [-e expire]
[-f inactive] [-g group] [-G group[,group]...]
[-K key=value] [-m [-z|-Z] [-k skel_dir]] [-p projname]
[-P profile[,profile]...] [-s shell] [-u uid [-o]] role

roleadd -D [-A authorization[,authorization]...]
[-b base_dir] [-e expire] [-f inactive] [-g group]
[-k skel_dir] [-K key=value] [-p projname]
[-P profile[,profile]...] [-s shell]

DESCRIPTION

roleadd adds a role entry to the /etc/passwd and /etc/shadow and
/etc/user_attr files. The -A and -P options respectively assign
authorizations and profiles to the role. The -p option associates a
project with the role. The -K option adds a key=value pair to
/etc/user_attr for the role. Multiple key=value pairs can be added
with multiple -K options.

roleadd also creates supplementary group memberships for the role (-G
option) and creates the home directory (-m option) for the role if
requested. The new role account remains locked until the passwd(1)
command is executed.

Specifying roleadd -D with the -A, -b, -e, -f, -g, -k, -K, -p, -P, or
-s option (or any combination of these options) sets the default
values for the respective fields. See the -D option. Subsequent
roleadd commands without the -D option use these arguments.

The system file entries created with this command have a limit of 512
characters per line. Specifying long arguments to several options can
exceed this limit.

roleadd requires that usernames be in the format described in
passwd(5). A warning message is displayed if these restrictions are
not met. See passwd(5) for the requirements for usernames.

To change the action of roleadd when the traditional login name
length limit of eight characters is exceeded, edit the file
/etc/default/useradd by removing the # (pound sign) before the
appropriate EXCEED_TRAD= entry, and adding it before the others.

OPTIONS

The following options are supported:

-A authorization

One or more comma separated authorizations defined in
auth_attr(5). Only a user or role who has grant rights to the
authorization can assign it to a role.

-b base_dir

The base directory for new role home directories (see the -d
option below). The directory named by base_dir must already exist
and be an absolute path.

-c comment

A text string. It is generally a short description of the role.
This information is stored in the role's /etc/passwd entry.

-d dir

The home directory of the new role. If not supplied, it defaults
to base_dir/account_name, where base_dir is the base directory
for new login home directories and account_name is the new role
name.

-D

Display the default values for group, base_dir, skel_dir, shell,
inactive, expire, proj, projname and key=value pairs. When used
with the -A, -b, -e, -f, -g, -P, -p, or -K, options, the -D
option sets the default values for the specified fields. The
default values are:

group

other (GID of 1)

base_dir

/home

skel_dir

/etc/skel

shell

/bin/pfsh

inactive

0

expire

Null

auths

Null

profiles

Null

proj

3

projname

default

key=value (pairs defined in user_attr(5))

not present

-e expire

Specify the expiration date for a role. After this date, no user
is able to access this role. The expire option argument is a date
entered using one of the date formats included in the template
file /etc/datemsk. See getdate(3C).

If the date format that you choose includes spaces, it must be
quoted. For example, you can enter 10/6/90 or October 6, 1990. A
null value (" ") defeats the status of the expired date. This
option is useful for creating temporary roles.

-f inactive

The maximum number of days allowed between uses of a role ID
before that ID is declared invalid. Normal values are positive
integers. A value of 0 defeats the status.

-g group

An existing group's integer ID or character-string name. Without
the -D option, it defines the new role's primary group membership
and defaults to the default group. You can reset this default
value by invoking roleadd -D -g group. GIDs 0-99 are reserved for
allocation by the Operating System.

-G group

One or more comma-separated existing groups, specified by integer
ID or character-string name. It defines the new role's
supplementary group membership. Any duplicate groups between the
-g and -G options are ignored. No more than NGROUPS_MAX groups
can be specified. GIDs 0-99 are reserved for allocation by the
Operating System.

-k skel_dir

A directory that contains skeleton information (such as .profile)
that can be copied into a new role's home directory. This
directory must already exist. The system provides the /etc/skel
directory that can be used for this purpose.

-K key=value

A key=value pair to add to the role's attributes. Multiple -K
options may be used to add multiple key=value pairs. The generic
-K option with the appropriate key may be used instead of the
specific implied key options (-A, -p, -P). See user_attr(5) for a
list of valid key=value pairs. The "type" key is not a valid key
for this option. Keys cannot be repeated.

-m [-z|-Z]

Create the new role's home directory if it does not already
exist. If the directory already exists, it must have read, write,
and execute permissions by group, where group is the role's
primary group.

If the parent directory of the role's home directory is located
on a separate ZFS file system and the /etc/default/useradd file
contains the parameter MANAGE_ZFS set to the value YES, a new ZFS
file system will be created for the role.

If the -z option is specified, roleadd will always try to create
a new file system for the home directory.

If the -Z option is specified, a new file system will never be
created.

-o

This option allows a UID to be duplicated (non-unique).

-p projname

Name of the project with which the added role is associated. See
the projname field as defined in project(5).

-P profile

One or more comma-separated execution profiles defined in
prof_attr(5).

-s shell

Full pathname of the program used as the role's shell on login.
It defaults to an empty field causing the system to use /bin/pfsh
as the default. The value of shell must be a valid executable
file.

-u uid

The UID of the new role. This UID must be a non-negative decimal
integer below MAXUID as defined in <sys/param.h>. The UID
defaults to the next available (unique) number above the highest
number currently assigned. For example, if UIDs 100, 105, and 200
are assigned, the next default UID number will be 201. UIDs 0-99
are reserved for allocation by the Operating System.

ATTRIBUTES

DIAGNOSTICS

In case of an error, roleadd prints an error message and exits with a
non-zero status.

The following indicates that login specified is already in use:

UX: roleadd: ERROR: login is already in use. Choose another.

The following indicates that the uid specified with the -u option is
not unique:

UX: roleadd: ERROR: uid uid is already in use. Choose another.

The following indicates that the group specified with the -g option
is already in use:

UX: roleadd: ERROR: group group does not exist. Choose another.

The following indicates that the uid specified with the -u option is
in the range of reserved UIDs (from 0-99):

UX: roleadd: WARNING: uid uid is reserved.

The following indicates that the uid specified with the -u option
exceeds MAXUID as defined in <sys/param.h>:

UX: roleadd: ERROR: uid uid is too big. Choose another.

The following indicates that the /etc/passwd or /etc/shadow files do
not exist:

UX: roleadd: ERROR: Cannot update system files - login cannot be created.

NOTES

If a network nameservice is being used to supplement the local
/etc/passwd file with additional entries, roleadd cannot change
information supplied by the network nameservice.
