.SH DESCRIPTION
.sp
.LP
\fBuseradd\fR adds a new user to the \fB/etc/passwd\fR and \fB/etc/shadow\fR
and \fB/etc/user_attr\fR files. The \fB-A\fR and \fB-P\fR options respectively
assign authorizations and profiles to the user. The \fB-R\fR option assigns
roles to a user. The \fB-p\fR option associates a project with a user. The
\fB-K\fR option adds a \fIkey=value\fR pair to \fB/etc/user_attr\fR for the
user. Multiple \fIkey=value\fR pairs may be added with multiple \fB-K\fR
options.
.sp
.LP
\fBuseradd\fR also creates supplementary group memberships for the user
(\fB-G\fR option) and creates the home directory (\fB-m\fR option) for the user
if requested. The new login remains locked until the \fBpasswd\fR(1) command is
executed.
.sp
.LP
Specifying \fBuseradd\fR \fB-D\fR with the \fB-s\fR, \fB-k\fR,\fB-g\fR,
\fB-b\fR, \fB-f\fR, \fB-e\fR, \fB-A\fR, \fB-P\fR, \fB-p\fR, \fB-R\fR, or
\fB-K\fR option (or any combination of these options) sets the default values
for the respective fields. See the \fB-D\fR option, below. Subsequent
\fBuseradd\fR commands without the \fB-D\fR option use these arguments.
.sp
.LP
The system file entries created with this command have a limit of 2048
characters per line. Specifying long arguments to several options can exceed
this limit.
.sp
.LP
\fBuseradd\fR requires that usernames be in the format described in
\fBpasswd\fR(4). A warning message is displayed if these restrictions are not
met. See \fBpasswd\fR(4) for the requirements for usernames.
.SH OPTIONS

.ne 2
.na
\fB\fB-A\fR \fIauthorization\fR\fR
.ad

an account.
.RE

.sp

.na
\fB\fB-b\fR \fIbase_dir\fR\fR
.ad
.sp .6
.RS 4n
The base directory for new login home directories (see the \fB-d\fR option
below. When a new user account is being created, \fIbase_dir\fR must already
exist unless the \fB-m\fR option or the \fB-d\fR option is also specified.
.RE

.sp
.ne 2
.na
\fB\fB-c\fR \fIcomment\fR\fR
.ad
.sp .6
.RS 4n
Any text string. It is generally a short description of the login, and is
currently used as the field for the user's full name. This information is
stored in the user's \fB/etc/passwd\fR entry.
.RE

.sp
.ne 2
.na
\fB\fB-d\fR \fIdir\fR\fR
.ad
.sp .6
.RS 4n
The home directory of the new user. It defaults to
\fIbase_dir\fR/\fIaccount_name\fR, where \fIbase_dir\fR is the base directory
for new login home directories and \fIaccount_name\fR is the new login name.
.RE

.sp

\fB\fB-D\fR\fR

Display the default values for \fBgroup\fR, \fBbase_dir\fR, \fBskel_dir\fR,
\fBshell\fR, \fBinactive\fR, \fBexpire\fR, \fBproj\fR, \fBprojname\fR and
\fBkey=value\fR pairs. When used with the \fB-g\fR, \fB-b\fR, \fB-f\fR,
\fB-e\fR, \fB-A\fR, \fB-P\fR, \fB-p\fR, \fB-R\fR, or \fB-K\fR options, the
\fB-D\fR option sets the default values for the specified fields. The default

\fB\fB-e\fR \fIexpire\fR\fR
.ad
.sp .6
.RS 4n
Specify the expiration date for a login. After this date, no user will be able
to access this login. The expire option argument is a date entered using one of
the date formats included in the template file \fB/etc/datemsk\fR. See
\fBgetdate\fR(3C).
.sp
If the date format that you choose includes spaces, it must be quoted. For
example, you can enter \fB10/6/90\fR or \fBOctober 6, 1990\fR. A null value
(\fB" "\fR) defeats the status of the expired date. This option is useful for
creating temporary logins.
.RE

.sp
.ne 2
.na
\fB\fB-f\fR \fIinactive\fR\fR
.ad
.sp .6
.RS 4n
The maximum number of days allowed between uses of a login ID before that
\fBID\fR is declared invalid. Normal values are positive integers. A value of
\fB0\fR defeats the status.
.RE

.sp
.ne 2
.na
\fB\fB-g\fR \fIgroup\fR\fR
.ad
.sp .6
.RS 4n
An existing group's integer \fBID\fR or character-string name. Without the
\fB-D\fR option, it defines the new user's primary group membership and
defaults to the default group. You can reset this default value by invoking
\fBuseradd\fR \fB-D\fR \fB-g\fR \fIgroup\fR. GIDs 0-99 are reserved for
allocation by the Solaris Operating System.
.RE

.sp
.ne 2
.na
\fB\fB-G\fR \fIgroup\fR\fR
.ad
.sp .6
.RS 4n
An existing group's integer \fBID\fR or character-string name. It defines the
new user's supplementary group membership. Duplicates between \fIgroup\fR with
the \fB-g\fR and \fB-G\fR options are ignored. No more than \fBNGROUPS_MAX\fR
groups can be specified. GIDs 0-99 are reserved for allocation by the Solaris
Operating System.
.RE

.sp
.ne 2
.na
\fB\fB-K\fR \fIkey=value\fR\fR
.ad
.sp .6
.RS 4n
A \fIkey=value\fR pair to add to the user's attributes. Multiple \fB-K\fR
options may be used to add multiple \fIkey=value\fR pairs. The generic \fB-K\fR
option with the appropriate key may be used instead of the specific implied key
options (\fB-A\fR, \fB-P\fR, \fB-R\fR, \fB-p\fR). See \fBuser_attr\fR(4) for a
list of valid \fIkey=value\fR pairs. The "type" key is not a valid key for this
option. Keys may not be repeated.
.RE

.sp
.ne 2
.na
\fB\fB-k\fR \fIskel_dir\fR\fR
.ad
.sp .6
.RS 4n
A directory that contains skeleton information (such as \fB\&.profile\fR) that
can be copied into a new user's home directory. This directory must already
exist. The system provides the \fB/etc/skel\fR directory that can be used for
this purpose.
.RE

.sp
.ne 2
.na
\fB\fB-m\fR\fR
.ad
.sp .6
.RS 4n
Create the new user's home directory if it does not already exist. If the
directory already exists, it must have read, write, and execute permissions by
\fIgroup\fR, where \fIgroup\fR is the user's primary group.
.RE

.sp
.ne 2
.na
\fB\fB-o\fR\fR
.ad
.sp .6
.RS 4n
This option allows a \fBUID\fR to be duplicated (non-unique).
.RE

.sp
.ne 2
.na
\fB\fB-P\fR \fIprofile\fR\fR
.ad
.sp .6
.RS 4n
One or more comma-separated execution profiles defined in \fBprof_attr\fR(4).
.RE

.sp
.ne 2
.na
\fB\fB-p\fR \fIprojname\fR\fR
.ad
.sp .6
.RS 4n
Name of the project with which the added user is associated. See the
\fIprojname\fR field as defined in \fBproject\fR(4).
.RE

.sp
.ne 2
.na
\fB\fB-R\fR \fIrole\fR\fR
.ad
.sp .6
.RS 4n
One or more comma-separated execution profiles defined in \fBuser_attr\fR(4).
Roles cannot be assigned to other roles.
.RE

.sp
.ne 2
.na
\fB\fB-s\fR \fIshell\fR\fR
.ad
.sp .6
.RS 4n
Full pathname of the program used as the user's shell on login. It defaults to
an empty field causing the system to use \fB/bin/sh\fR as the default. The
value of \fIshell\fR must be a valid executable file.
.RE

.sp
.ne 2
.na
\fB\fB-u\fR \fIuid\fR\fR
.ad
.sp .6
.RS 4n
The \fBUID\fR of the new user. This \fBUID\fR must be a non-negative decimal
integer below \fBMAXUID\fR as defined in \fB<sys/param.h>\fR\&. The \fBUID\fR
defaults to the next available (unique) number above the highest number
currently assigned. For example, if \fBUID\fRs 100, 105, and 200 are assigned,
the next default \fBUID\fR number will be 201. \fBUID\fRs \fB0\fR-\fB99\fR are
reserved for allocation by the Solaris Operating System.

.SH NOTES
.sp
.LP
The \fBuseradd\fR utility adds definitions to only the local \fB/etc/group\fR,
\fBetc/passwd\fR, \fB/etc/passwd\fR, \fB/etc/shadow\fR, \fB/etc/project\fR, and
\fB/etc/user_attr\fR files. If a network name service such as \fBNIS\fR or
\fBNIS+\fR is being used to supplement the local \fB/etc/passwd\fR file with
additional entries, \fBuseradd\fR cannot change information supplied by the
network name service. However \fBuseradd\fR will verify the uniqueness of the
user name (or role) and user id and the existence of any group names specified
against the external name service.
