Enable the password change dialog within the AppSuite Frontend

After the installation of the package, you must explicitly enable the password change dialog for each AppSuite user. The simplest option to do this, is executing the following command:

/opt/open-xchange/sbin/changeuser -c <_context_id_> -u <_user_name_> --access-edit-password on

You can also use all other AppSuite provisioning interfaces like JAVA RMI or SOAP. Please review the corresponding documentation for each interface for details.

Example

In /opt/open-xchange/etc/change_pwd_script.properties add this line:

com.openexchange.passwordchange.script.shellscript=/bin/pwchange.pl

Example Script 1

This example script calls saslpasswd to change the password in the sasldb:

#! /usr/bin/perl -w -T
#
# perlsec(1) for security related perl programming
#
use Getopt::Long;
use strict;

my $user;
my $pw;
my $result;
my $cid;
my $oldpassword;
my $userid;

open(LOG, '>>/var/log/pw.log'); 

sub log_error {
       my $errorstring=$_[0];
       print LOG "Error: $errorstring\n";
       die "$errorstring";
}
# secure env
$ENV{'PATH'} = "";
$ENV{'ENV'} = "";

$result = GetOptions ("username=s" => \$user,
                     "cid" => \$cid,
                     "userid" => \$userid,
                     "oldpassword" => \$oldpassword,
                     "newpassword=s" => \$pw);

$user || &log_error("missing parameter username");
print LOG "changing password for user $user\n";
$pw || &log_error("missing parameter newpassword");

my $usersav = $user;

# add a taint check
if ($user =~ /^([-\@\w.]+)$/) {
 $user = $1;                     # $data now untainted
} else {
 &log_error("Bad data in '$user'");
}

die "Can't fork: $!" unless defined(my $pid = open(KID, "|-"));
if ($pid) {           # parent
 print KID $pw;
 close KID;
} else {
 exec '/usr/bin/sudo', '/usr/sbin/saslpasswd2', '-p', "$user"
   or &log_error("can't exec myprog: $!");
}
close(LOG);

Example Script 2

The following script uses ldappasswd to change the password in an LDAP server.

#!/bin/bash
ldappasswd -h my_ldap_server -D "uid=$4,ou=people,dc=example,dc=com" -w $8 \
   -s ${10} "uid=$4,ou=people,dc=example,dc=com"

Example Script 3

The following script uses open-xchange-passwordchange-script data to change the password within LDAP

#!/usr/bin/perl -w     
# Begin LDAP Stuff
       use Net::LDAP;
       use Net::LDAP::Extension::SetPassword;
my $cid = $ARGV[1];
my $userid = $ARGV[5];
my $oldpw = $ARGV[7];
my $hostname= 'localhost';
my $rootdn= 'cn=Administrator,dc=example,dc=com';
my $userbind= 'ou=People,dc=example,dc=com';
my $adminpasswd='system';
my $name= $ARGV[3];
my $newpasswd= $ARGV[9];
my $ldap = Net::LDAP->new("$hostname")
or die "Host not found: $!";

open(LOG, '>>/var/log/open-xchange/pw.log');  
 
sub log_error {
      my $errorstring=$_[0];
      print LOG "Error: $errorstring\n";
      die "$errorstring";
}
 
$name || &log_error("missing parameter username");
print LOG "changing password for $ARGV[2]: $name with $ARGV[0]: $cid and $ARGV[4]: $userid\n";
$newpasswd || &log_error("missing parameter newpassword");
 
 $ldap->bind( "$rootdn", password => "$adminpasswd" );

my $mesg = $ldap->set_password(
   newpasswd => "$newpasswd",
   user      => "uid=$name,$userbind"
   );
 
  die "error: ", $mesg->code(), ": ", $mesg->error() if ( $mesg->code() );
  close(LOG);
