ROLEADD(1M) Maintenance Commands ROLEADD(1M)


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(4).
A warning message is displayed if these restrictions are not met. See
passwd(4) 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(4).
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(4))

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(4) 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(4).


-P profile

One or more comma-separated execution profiles defined in
prof_attr(4).


-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.

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.
