=head1 NAME

       smbldap-usermod.pl - Modify a user account

=head1 SYNOPSIS

       smbldap-usermod.pl [-c comment] [-d home_dir]
               [-g initial_group] [-G group[,...]]
               [-l login_name] [-p passwd]
               [-s shell] [-u uid [ -o]] [-x]
               [-A canchange] [-B mustchange] [-C smbhome]
               [-D homedrive] [-E scriptpath] [-F profilepath]
               [-H acctflags] login

=head1 DESCRIPTION

       The  smbldap-usermod.pl  command  modifies the system account files
       to reflect the changes that are specified on the  command  line.
       The  options  which apply to the usermod command are

       -c comment
              The new value of the user's comment field (gecos).

       -d home_dir
              The user's new login directory.

       -g initial_group
              The group name or number of the user's new initial login  group.
              The  group  name  must  exist.   A group number must refer to an
              already existing group.  The default group number is 1.

       -G group,[...]
              A list of supplementary groups which the user is also  a  member
              of.   Each  group is separated from 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.  If the user
              is currently a member of a group which is not listed,  the  user
              will be removed from the group

       -l login_name
              The  name  of the user will be changed from login to login_name.
              Nothing else is changed.  In particular, the user's home  direc­
              tory  name  should  probably be changed to reflect the new login
              name.

       -s shell
              The name of the user's new login shell.  Setting this  field  to
              blank causes the system to select the default login shell.

       -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  non-
              negative.  Any files which the user owns  and  which  are
              located  in  the directory tree rooted at the user's home direc­
              tory will have the file user ID  changed  automatically.   Files
              outside of the user's home directory must be altered manually.

       -x     Creates rid and primaryGroupID in hex instead of decimal (for 
              Samba 2.2.2 unpatched only - higher versions always use decimal)

       -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]')

       -I     disable user. Can't be used with -H or -J

       -J     enable user. Can't be used with -H or -I
