Installation¶

From tarball¶

Uncompress and unarchive the tarball:

tar -zxvf ltb-project-service-desk-*.tar.gz

Install files in /usr/share/:

mv ltb-project-service-desk-* /usr/share/service-desk

You need to install these prerequisites:

Apache or another web server
php
php-ldap
Smarty (version 3)

Debian / Ubuntu¶

Configure the repository:

vi /etc/apt/sources.list.d/ltb-project.list

deb [arch=amd64] https://ltb-project.org/debian/stable stable main

Import repository key:

wget -O - https://ltb-project.org/documentation/_static/RPM-GPG-KEY-LTB-project | sudo apt-key add -

Then update:

apt update

You are now ready to install:

apt install service-desk

CentOS / RedHat¶

Warning

You may need to install first the package php-Smarty which is not in official repositories.

Configure the yum repository:

vi /etc/yum.repos.d/ltb-project.repo

[ltb-project-noarch]
name=LTB project packages (noarch)
baseurl=https://ltb-project.org/rpm/$releasever/noarch
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-LTB-project

Then update:

yum update

Import repository key:

rpm --import https://ltb-project.org/documentation/_static/RPM-GPG-KEY-LTB-project

You are now ready to install:

yum install service-desk

Docker¶

Prepare a local configuration file for Self Service Password, for example /home/test/servicedesk.conf.php.

Start container, mounting that configuration file:

docker run -p 80:80 \
    -v /home/test/servicedesk.conf.php:/var/www/conf/config.inc.local.php \
    -it docker.io/ltbproject/service-desk:latest

Apache configuration¶

Virtual host¶

Here is a sample virtual host configuration:

<VirtualHost *:80>
   ServerName sd.example.com

   DocumentRoot /usr/share/service-desk/htdocs
   DirectoryIndex index.php

   <Directory /usr/share/service-desk/htdocs>
       AllowOverride None
       Require all granted
   </Directory>

   LogLevel warn
   ErrorLog /var/log/apache2/sd_error.log
   CustomLog /var/log/apache2/sd_access.log combined
</VirtualHost>

Tip

The application can also be published in a directory inside the default host

Warning

You must protect the access to the application, else everyone will be able to reset any user password!

LDAP authentication and authorization¶

You can use Apache mod_authnz_ldap. This module checks user credentials against the LDAP directory and can restrict access to users or groups.

<Directory /usr/share/service-desk/htdocs>
    AllowOverride None
    AuthType basic
    AuthName "LTB Service Desk"
    AuthBasicProvider ldap
    AuthLDAPURL ldap://ldap.example.com/dc=example,dc=com?uid
    Require ldap-group cn=support,ou=groups,dc=example,dc=com
</Directory>

External authentication¶

You can use any authentication source and authentication protocols, like CAS, SAML or OpenID Connect. Configuring these solutions is out of scope of the current documentation.

General parameters¶

Configuration files¶

The default configuration file is conf/config.inc.php, it contains all default values. To edit configuration, you should create conf/config.inc.local.php and override needed parameters:

<?php
// Override config.inc.php parameters below

?>

Warning

Do not copy config.inc.php into config.inc.local.php, as the first one includes the second. You would then create an infinite loop and crash your application.

Multi tenancy¶

You can load a specific configuration file by passing a HTTP header. This feature is disable by default. To enable it:

$header_name_extra_config = "SSP-Extra-Config";

Then if you send the header SSP-Extra-Config: domain1, the file conf/config.inc.domain1.php will be loaded.

Using Apache, we may set such header using the following:

<VirtualHost *:80>
   ServerName ssp.domain1.com
   RequestHeader setIfEmpty SSP-Extra-Config domain1
   [...]
</VirtualHost>

Using Nginx, we could use instead:

server {
    [...]
    location ~ \.php {
        fastcgi_param HTTP_SSP_EXTRA_CONFIG domain1;
        [...]
    }

Language¶

Tip

Lang is selected from browser configuration. If no matching language is found, the default language is used.

Set default language in $lang:

$lang = "en";

Tip

You can override messages by creating lang files in conf/, for example conf/en.inc.php.

Dates¶

You can adapt how dates are displayed with specifiers (see strftime reference):

$date_specifiers = "%Y-%m-%d %H:%M:%S (%Z)";

Graphics¶

Logo¶

You change the default logo with your own. Set the path to your logo in $logo:

$logo = "images/ltb-logo.png";

Background¶

You change the background image with your own. Set the path to image in $background_image:

$background_image = "images/unsplash-space.jpeg";

Custom CSS¶

To easily customize CSS, you can use a separate CSS file:

$custom_css = "css/custom.css";

Debug¶

You can turn on debug mode with $debug:

$debug = true;

Tip

Debug messages will be printed in server logs.

This is also possible to enable Smarty debug, for web interface issues:

$smarty_debug = true;

Tip

Debug messages will appear on web interface.

Smarty¶

You need to define where Smarty is installed:

define("SMARTY", "/usr/share/php/smarty3/Smarty.class.php");

Notify administrator by mail¶

It is possible to provide mail of administrator to service-desk using a HTTP header.

$header_name_notify_admin_by_mail is name of header that will be provided to cgi script as HTTP_$header_name_notify_admin_by_mail to set administrator mail from webserver.

$header_name_notify_admin_by_mail = "SSP-Admin-Mail";

Using Apache, we may set such header using the following:

<VirtualHost *:80>
   ServerName ssp.domain1.com
   RequestHeader setIfEmpty SSP-Admin-Mail admin@example.com
   [...]
</VirtualHost>

Using Nginx, nginx take normalized cgi param naming, ie uppercase and - replaced to _. we could use instead:

server {
    [...]
    location ~ \.php {
        fastcgi_param HTTP_SSP_ADMIN_MAIL admin@example.com;
        [...]
    }

LDAP parameters¶

Server address¶

Use an LDAP URI to configure the location of your LDAP server in $ldap_url:

$ldap_url = "ldap://localhost:389";

You can set several URI, so that next server will be tried if the previous is down:

$ldap_url = "ldap://server1 ldap://server2";

To use SSL, set ldaps in the URI:

$ldap_url = "ldaps://localhost";

To use StartTLS, set true in $ldap_starttls:

$ldap_starttls = true;

Tip

LDAP certificate management in PHP relies on LDAP system libraries. Under Linux, you can configure /etc/ldap.conf (or /etc/ldap/ldap.conf on Debian/Ubuntu, or C:\OpenLDAP\sysconf\ldap.conf for Windows). Provide the certificate from the certificate authority that issued your LDAP server’s certificate.

Credentials¶

Configure DN and password in $ldap_bindn and $ldap_bindpw:

$ldap_binddn = "cn=manager,dc=example,dc=com";
$ldap_bindpw = "secret";

Tip

You can use the LDAP admin account or any service account. The account needs to read users, password policy entries and write userPassword and pwdReset attributes in user entries. Note that using the LDAP admin account will bypass any password policy like minimal size or password history when reseting the password.

LDAP Base¶

You can set global base in $ldap_base:

$ldap_base = "dc=example,dc=com";

User search parameters¶

You can set base of the search in $ldap_user_base:

$ldap_user_base = "ou=users,".$ldap_base;

The filter can be set in $ldap_user_filter:

$ldap_user_filter = "(objectClass=inetOrgPerson)";

Size limit¶

It is advised to set a search limit on client side if no limit is set by the server:

$ldap_size_limit = 100;

Default password policy¶

Set $ldap_default_ppolicy value if a default policy is configured in your LDAP directory.

$ldap_default_ppolicy = "cn=default,ou=ppolicy,dc=example,dc=com";

Tip

Password policy is first searched in pwdPolicySubentry attribute of user entry, then fallback to default policy.

Attributes¶

Attributes are defined in $attributes_map, where each item is an array with these keys:

attribute: name of LDAP attribute, in lower case
faclass: name of Font Awesome icon class
type: type of attribute (text, mailto, tel or date)

This is used to configure how attribute is displayed.

Available types:

text: simple text
mailto: mailto link
tel: tel link
boolean: true or false
date: LDAP date converted to full date
list: value from a list
bytes: bytes converted in KB/MB/GB/TB
timestamp: timestamp converted to full date
dn_link: convert DN into link to account display page
address: convert address string to multi-lines

Tip

See LDAP Tool Box White Pages documentation to get more information.

Search parameters¶

Search attributes¶

Configure attributes on which the search is done:

$search_attributes = array('uid', 'cn', 'mail');

By default, search is done with substring match. This can be changed to use exact match:

$search_use_substring_match = false;

Results display¶

Configure items shown when displaying results:

search_result_items = array('identifier', 'mail', 'mobile');

Datatables¶

Define pagination values in dropdown:

$datatables_page_length_choices = array(10, 25, 50, 100, -1); // -1 means All

Set default pagination for results (can also be used to force the length without $datatables_page_length_choices):

$datatables_page_length_default = 10;

Enable or disable autoPrint feature:

$datatables_auto_print = true;

Display parameters¶

User panel¶

Configure which items are displayed:

$display_items = array('identifier', 'firstname', 'lastname', 'title', 'businesscategory', 'employeenumber', 'employeetype', 'mail', 'phone', 'mobile', 'fax', 'postaladdress', 'street', 'postalcode', 'l', 'state', 'organizationalunit', 'organization');

Set which item is use as title:

$display_title = "fullname";

Choose to show undefined values:

$display_show_undefined = false;

Account information panel¶

Configure which items are displayed:

$display_password_items = array('pwdchangedtime', 'pwdreset', 'pwdaccountlockedtime', 'pwdfailuretime','pwdpolicysubentry', 'authtimestamp', 'created', 'modified');

You can also display the password expiration date in this panel by enabling this option:

$display_password_expiration_date = true;

Check password¶

This feature allows to enter a password and check authentication.

Warning

the authentification can fail even if the password is correct. This is the case if account is locked or password is expired.

To enable this feature:

$use_checkpassword = true;

Reset password¶

This feature allows to reset a password and set the reset at next connection flag.

To enable this feature:

$use_resetpassword = true;

When changing the password, you can force the user to reset it at next connection. To configure the default value presented in the form:

$resetpassword_reset_default = true;

If you do not want to let the choice to reset at next connection, you can hide this button:

$use_resetpassword_resetchoice = false;

In this case, the value set in $resetpassword_reset_default will be applied.

Notify user by mail¶

You can notify the user by mail when the password is reset:

$notify_on_change = true;

To do so you need to configure mail (see Mail).

Notify administrator by mail¶

$notify_admin_by_mail_list is a a php array list of mails of admins to set directly in service-desk configuration.

$header_name_notify_admin_by_mail is name of header that will be provided to cgi script as HTTP_$header_name_notify_admin_by_mail to set administrator mail from webserver. This setting allows webserver to select an administrator mail related to current http session. Its value should be a valid mail according to rfc822

If those are set any administrator mail will receive a notification that user password was changed.

Remark this is not controled by $notify_on_change, which is only for user.

$notify_admin_by_mail_list=array( 'a@example.com','b@example.com' 'c@example.com');
$header_name_notify_admin_by_mail=SD_ADMIN_MAIL;

To do so you need to configure mail (see Mail).

Lock account¶

This feature allows to lock the account permanently. The button is only displayed if the account is not locked.

To enable this feature:

$use_lockaccount = true;

Unlock account¶

This feature allows to unlock the account. It is only displayed if the account is already locked.

To enable this feature:

$use_unlockaccount = true;

Hook¶

Hook feature allows to run a script before or after the password modification.

The script is called with two parameters: login and new password.

Parameters¶

Define prehook or posthook script (and enable the feature):

$prehook = "/usr/share/service-desk/prehook.sh";
$posthook = "/usr/share/service-desk/posthook.sh";

Define which attribute will be used as login:

$prehook_login = "uid";
$posthook_login = "uid";

You can choose to display an error if the script return code is greater than 0:

$display_prehook_error = true;
$display_posthook_error = true;

The displayed message will be the first line of the script output.

Another option can be enabled to encode the password in base64 before sending it to the script, which can avoid an execution issue if the password contains special characters:

$prehook_password_encodebase64 = false;
$posthook_password_encodebase64 = false;

By default with prehook script, the password will not be changed in LDAP directory if the script fails. You can change this behavior to ignore script error. This could be useful to run prehook script and display a warning if it fails, but still try to update password in the directory.

$ignore_prehook_error = true;

Dashboards¶

Locked accounts¶

This page will list all currently locked accounts.

To enable it:

$use_searchlocked = true;

It is possible to unlock an account directly from this page. This requires to enable the feature Unlock account.

Soon expired passwords¶

This page will list all accounts with a password that will expire in the next days.

To enable it:

$use_searchwillexpire = true;

You can also configure the number of days before expiration:

$willexpiredays = 14;

Expired passwords¶

This page will list all accounts with an expired password.

To enable it:

$use_searchexpired = true;

Idle accounts¶

This page will list all accounts never connected, or not connected since a number of days.

Tip

This requires the authTimestamp attribute which is provided by the lastbind overlay.

To enable it:

$use_searchidle = true;

You can also configure the number of idle days:

$idledays = 60;

Mail¶

LDAP Attributes¶

Set the LDAP attributes where user email may be stored:

$mail_attributes = array( "mail", "gosaMailAlternateAddress", "proxyAddresses" );

Tip

Only the first value of this attribute will be used to get the mail address.

You can also define which LDAP attribute contains the user name (will be used in mail body content):

$mail_username_attribute = "cn";

Sender name¶

You can change the default From header and add a signature:

$mail_from = "admin@example.com";
$mail_from_name = "Self Service Password administrator";
$mail_signature = "";

Change password notification¶

Use this option to send a confirmation mail to the user, just after a successful password change:

$notify_on_change = true;

This option is false by default.

PHPMailer¶

You have to set all parameters for PHPMailer if you use mail notificaiton.

$mail_sendmailpath = '/usr/sbin/sendmail';
$mail_protocol = 'smtp';
$mail_smtp_debug = 0;
$mail_debug_format = 'html';
$mail_smtp_host = 'localhost';
$mail_smtp_auth = false;
$mail_smtp_user = '';
$mail_smtp_pass = '';
$mail_smtp_port = 25;
$mail_smtp_timeout = 30;
$mail_smtp_keepalive = false;
$mail_smtp_secure = 'tls';
$mail_smtp_autotls = true;
$mail_smtp_options = array();
$mail_contenttype = 'text/plain';
$mail_wordwrap = 0;
$mail_charset = 'utf-8';
$mail_priority = 3;

Tip

See https://github.com/PHPMailer/PHPMailer for more information

Audit¶

You can enable audit to log all actions done through Service Desk.

Audit log file¶

Set the file where actions are logged:

$audit_log_file = "/var/log/service-desk/audit.log";

Tip

The file must be writable by the PHP or WebServer process

Admin name¶

The admin name must be set into an HTTP header.

$header_name_audit_admin = "Auth-User";

Tip

If no header defined or if header is empty, actions will be logged as “anonymous”
