# This script has been taken von smbldap-tools 0.9.5, its original name
# is smbldap-useradd. It has been modified so that machine accounts can 
# be created and so that they will be compliant to the pre-requisites of 
# GOsa as in Debian Edu.
#
# This script depends on package smbldap-tools (i.e. on its
# smbldap_tool.pm).
#
# Modifcations have been done by several people, initially by
#    Mike Gabriel <mike.gabriel@das-netzwerkteam.de>

smbldap-useradd - Create a new user

=head1 SYNOPSIS

smbldap-useradd [-o user_ou] [-c comment] [-d home_dir] [-g initial_group] [-G group[,...]] [-m [-k skeleton_dir]] [-s shell] [-u uid [ -o]] [-P] [-A canchange] [-B mustchange] [-C smbhome] [-D homedrive] [-E scriptpath] [-F profilepath] [-H acctflags] login

=head1 DESCRIPTION

Creating New Users
The smbldap-useradd command creates a new user account using  the values specified on the  command  line  and  the default  values from the system and from the configuration files (in  /etc/smbldap-tools directory).

For Samba users, rid is '2*uidNumber+1000', and sambaPrimaryGroupSID  is '$SID-2*gidNumber+1001', where $SID is the domain SID.  Thus you may want to use :
$ smbldap-useradd -a -g "Domain Admins" -u 500 Administrator
to create an domain administrator account (admin rid is 0x1F4 = 500 and grouprid is 0x200 = 512).

Without any option, the account created will be an Unix (Posix)  account. The following options may be used to add information:

-o node
   The user's account will be created in the specified organazional unit. It is relative to the user suffix dn ($usersdn) defined in the configuration file.
Ex: 'ou=admin,ou=all'

-a
   The user will have a Samba account (and Unix).

-b
   The usrer is an AIX acount

-w
   Creates an account for a Samba machine (Workstation), so that it can join a sambaDomainName.

-i
   Creates an interdomain trust account (machine Workstation). A password will be asked for the trust account.

-c "comment"
   The new user's comment field (gecos). This option is for gecos only! To set as user's full name use the -N and -S options.

-d home_dir
   The new user will be created using home_dir as the value for the user's login directory.  The default is to append the login name      to userHomePrefix (defined in the configuration file) and use that      as the login directory name.

-g initial_group
   The group name or number of the user's initial login group. The  group  name must exist.  A group number must refer to an already  existing group.  The default group number is defined in the  configuration file (defaultUserGid="513").

-G group,[...]
   A list of supplementary groups which the user is also  a  member of. Each  group is separated to the next by a comma, with no intervening whitespace.  The groups  are  subject  to  the  same restrictions as the group given with the -g option.  The default is for the user to belong only to the initial group.

-m
   The user's home directory will be created if it does not  exist. The  files  contained in skeletonDir will be copied to the home directory if the -k option is used,  otherwise  the  files  contained  in /etc/skel will be used instead.  Any directories contained in skeletonDir or  /etc/skel  will  be  created  in  the user's  home  directory as well.  The -k option is only valid in conjunction with the -m option.  The default is  to  not  create the directory and to not copy any files.

-s shell
   The name of the user's login shell.  The  default  is  to  leave this  field blank, which causes the system to select the default login shell.

-t time
   Wait <time> seconds before exiting script when adding computer's account. This is useful when Master/PDC and Slaves/BDCs are connected through the internet (replication is not real time)

-u uid
   The numerical value of  the  user's  ID.   This  value  must  be unique,  unless  the  -o option is used.  The value must be nonnegative.  The default is to use the smallest ID  value  greater than 1000 and greater than every other user.

-P
   ends by invoking smbldap-passwd

-A
   can change password ? 0 if no, 1 if yes

-B
   must change password ? 0 if no, 1 if yes

-C sambaHomePath
   SMB home share, like '\\\\PDC-SRV\\homes'

-D sambaHomeDrive
   letter associated with home share, like 'H:'

-E sambaLogonScript
   relative to the [netlogon] share (DOS script to execute on login, like 'foo.bat'

-F sambaProfilePath
   profile directory, like '\\\\PDC-SRV\\profiles\\foo'

-H sambaAcctFlags
   spaces and trailing bracket are ignored (samba account control bits like '[NDHTUMWSLKI]'

-M mail
   local mail aliases (multiple addresses are seperated by spaces)

-N givenname
   family name. Defaults to username

-S surname
   defaults to username

-T mailToAddress
   Forward address (multiple addresses are seperated by spaces)

-n
   do not print banner message
