This stand-alone application collects information from a single LDAP Directory in order to automatically synchronize the persons and the users in iTop.

Main functions:

• Automatic creation and update of Persons and Users in iTop based on LDAP data.
• Automatic assignment of Profiles to Users based on LDAP groups (this is optional).

Technical aspects:

• The collector can reside on any system with web access to iTop and LDAP access to the LDAP Directory
• The collector is compatible with Windows Active Directory
• The definition of the mapping between LDAP fields and iTop fields is fully configurable.
• The creation of the Synchronization Data Sources in iTop is fully automated.

• The current version is synchronizing neither the Organizations nor the Locations.
• The location of person and the manager of a person are not synchronized.
• One collector is collecting data from one single LDAP directory instance only.

• PHP (command line interface), version 5.3.0 up to 7.2 with the php-ldap, php-dom and php-simplexml extensions installed.
• An LDAP access to the Enterprise directory and a read user to access the data.
• An HTTP/HTTPS access to the iTop web services (REST + synchro_import.php and synchro_exec.php)

• Expand the content of the zip archive “ldap-data-collector” in a folder on the machine that will run the collector application. This machine must have an LDAP access to the Enterprise directory and a web access to the iTop server.
• create the file conf/params.local.xml to suit your installation, supplying the appropriate credentials to connect to LDAP server and iTop.

By default this file should contains the values used to connect to the LDAP server and to the iTop server:

<parameters>
  <itop_url>http://localhost/</itop_url>
  <itop_login>admin</itop_login>
  <itop_password>admin</itop_password>
  <contact_to_notify>john.doe@demo.com</contact_to_notify>
  <synchro_user>admin</synchro_user>

  <ldapport>389</ldapport>
  <ldapdn>DC=company,DC=com</ldapdn>
  <ldaplogin>CN=ITOP-LDAP,DC=company,DC=com</ldaplogin>
  <ldappassword>password</ldappassword>
  <!--
    Set a non empty (and unique) prefix if you run several instances of the collector against the same iTop Server
    This is the recommended method to collect data from several LDAP servers. (assign a unique prefix to each "source" LDAP server)
    Note: this prefix can be set but do not touch the one inside json_placeholders
    -->
  <prefix></prefix>
  <json_placeholders>
    <full_load_interval>604800</full_load_interval><!-- 7 days (in seconds): 7*24*60*60 -->
    <synchro_status>production</synchro_status>
  </json_placeholders>
</parameters>

The default values for the configuration of the data collection is defined in the file collectors/params.distrib.xml. This configuration defines which LDAP queries are executed on the LDAP server to retrieve the data, how to map the LDAP fields with the iTop fields and some default values for the iTop fields.

The configuration looks as follows:

<parameters>
	<!-- Parameters for Person synchronization -->
	<ldappersonfilter>(objectClass=person)</ldappersonfilter>
	<person_fields>
		<!--  Mapping between LDAP fields and iTop Person's object fields -->
		<primary_key>samaccountname</primary_key>
		<name>sn</name>
		<first_name>givenname</first_name>
		<email>mail</email>
		<phone>telephonenumber</phone>
		<mobile_phone>mobile</mobile_phone>
		<function>title</function>
		<employee_number>employeenumber</employee_number>
	</person_fields>
	<person_defaults>
		<!--  Default values for iTop Person's object fields -->
		<org_id>Demo</org_id>
		<status>active</status>
	</person_defaults>
	<!-- Parameters for User synchronization -->
        <collect_person_only>no</collect_person_only>
	<ldapuserfilter>(&amp;(objectClass=person)(mail=*))</ldapuserfilter>
	<synchronize_profiles>no</synchronize_profiles>
        <itop_group_pattern>/^CN=itop-(.*),OU=.*/</itop_group_pattern>
	<user_fields>
		<!--  Mapping between LDAP fields and iTop UserLDAP's object fields -->
		<primary_key>samaccountname</primary_key>
		<login>samaccountname</login>
		<contactid>mail</contactid>
	</user_fields>
	<user_defaults>
		<!--  Default values for iTop UserLDAP's object fields -->
		<profile>Portal user</profile>
		<language>EN US</language>
	</user_defaults>
</parameters>

<person_fields>
  <primary_key>samaccountname</primary_key>
  <name>sn</name>
  <first_name>givenname</first_name>
  <email>mail</email>
  <phone>telephonenumber</phone>
  <mobile_phone>mobile</mobile_phone>
  <function>title</function>
  <employee_number>employeenumber</employee_number>
</person_fields>

<person_defaults>
  <org_id>Demo</org_id>
  <status>active</status>
</person_defaults>

<user_fields>
  <primary_key>samaccountname</primary_key>
  <login>samaccountname</login>
  <contactid>mail</contactid>
</user_fields>

<user_defaults>
  <profile>Portal user</profile>
  <language>EN US</language>
</user_defaults>

Those parameters can be redefined in the file conf/params.local.xml in order to take into account your specific needs. (For instance the mapping between iTop and LDAP attributes)

<user_defaults>
  <profile_list>profileid->name:name_of_profile1|profileid->name:name_of_profile2</profile_list>
  ...

You can test your configuration without importing any data in iTop by running the following command from the command line:

php exec.php --console_log_level=9 --collect_only

This produces an output similar to the one shown below:

Debug - OK, the required PHP version to run this application is 5.3.0. The current PHP version is 7.2.7-0ubuntu0.18.04.2.
Debug - OK, the required extension 'simplexml' is installed (current version: 7.2.7-0ubuntu0.18.04.2 >= 0.1).

   iTop 'name' is filled from LDAP 'sn' 
   iTop 'first_name' is filled from LDAP 'givenname' 
   iTop 'email' is filled from LDAP 'mail' 
   iTop 'phone' is filled from LDAP 'telephonenumber' 
   iTop 'mobile_phone' is filled from LDAP 'mobile' 
   iTop 'function' is filled from LDAP 'title' 
   iTop 'employee_number' is filled from LDAP 'employeenumber' 
   iTop 'org_id' is filled with the constant value 'Demo'
   iTop 'status' is filled with the constant value 'active'

Debug - LDAPUsers: Mapping of the fields:
   iTop 'primary_key' is filled from LDAP 'samaccountname' 
   iTop 'login' is filled from LDAP 'samaccountname' 
   iTop 'contactid' is filled from LDAP 'mail' 
   iTop 'language' is filled with the constant value 'EN US'
   iTop 'profile_list' is filled with the constant value 'profileid->name:Portal user'
  
...

You can see the order in which the configuration files were loaded and the resulting configuration.

If you are unsure of the mapping between the fields in your LDAP/AD server and iTop you can use the script ldap-test.php provided with the connector to dump the result of the LDAP query.

Once the connection to the LDAP server is properly configured on your conf/params.local.xml file, run the follwing script for the command line:

php collectors/bin/ldap-test.php

This produces the following output:

The LDAP query '(objectClass=person)' returned 345 elements.

The first column of the output is the name of the field in LDAP (all fields returned by the LDAP query are listed) and the second column shows the values of the first record found in LDAP. Based on the values displayed you can complete the configuration of the mapping in the configuration file conf/params.local.xml.

To launch the data collection and synchronization with iTop, run the following command (from the root directory where the data collector application is installed):

php exec.php

The following (optional) command line options are available:

The execution of the command line will:

1. Connect to iTop to create the Synchronization Data Sources (or check their definition if they already exist, updating them if needed)
2. Connect to the LDAP server to collect the information about the Persons and the Users
3. Upload the collected data into iTop
4. Synchronize the collected data with the existing iTop Person and Users.

When the collector is run, two Synchro Data Sources are created and used for synchrponizing Person and LDAPUser objects in iTop:

Once you've run the data collector interactively, the next step is to schedule its execution so that the collection and import occurs automatically at regular intervals.

The data collector does not provide any specific scheduling mechanism, but the simple command line php exec.php can be scheduled with either cron (on Linux systems) or using the Task Scheduler on Windows.

Between version 1.1.1 and 1.2.0 the structure of the configuration has slightly changed:

• The mapping of the fields between LDAP and iTop is now defined as an array <person_fields> for the Person object and <user_fields> for the LDAPUser object. The same applies to the default values for the fields which are respectively configured in the arrays <person_defaults> and <user_defaults>. If you changed the default configuration for these items, you'll have to adjust your configuration file accordingly.
• The parameter synchro_profils has been renamed to synchro_profiles
• The parameter synchronize_organization has been deprecated. If you don't want to synchronize the organizations, don't provide a mapping for the org_id field (in <person_fields>) and provide a default value for org_id in <person_defaults>.
• Version 1.1 did not support to run several instances of the collector against the same iTop instance (for multiple LDAP servers), and thus the name of the SQL tables holding the synchro data was using a different scheme. To retain the same name of the SQL data tables, edit the configuration file and put the folling line in the <json_placeholders> section:

	<json_placeholders>
		<prefix></prefix>
		<persons_data_table>synchro_data_PersonAD</persons_data_table>
		<users_data_table></users_data_table>
	</json_placeholders>

The current version of the Data collector for LDAP supports only one source LDAP server. However you can run several instances of the collector, each with a different configuration to connect to different LDAP servers but the to the same iTop instance.

In such a configuration, make sure that the <prefix> parameter is different for each LDAP server, since each collector needs to create its own set of the Synchro Data Sources in iTop.

Create two copies of the LDAP data collector: collector-ldap1 and collector-ldap2. In collector-ldap1/conf/params.local.xml put:

<parameters>
	...
	<ldaphost>ldap-server1.demo.com</ldaphost>
	<ldapport>389</ldapport>
	<prefix>ldap1_</prefix> <!-- IMPORTANT to have a unique prefix, use only [a-z0-9_] characters -->
</parameters>

In collector-ldap2/conf/params.local.xml put:

<parameters>
	...
	<ldaphost>ldap-server2.demo.com</ldaphost>
	<ldapport>389</ldapport>
	<prefix>ldap2_</prefix> <!-- IMPORTANT to have a unique prefix, use only [a-z0-9_] characters -->
</parameters>

This will create two independent sets of Synchronization Data Sources:
