<title>Adding LDAP access</title>

<p>The LDAP protocol was created to let users share contact information over a network by sharing access to a central directory. LDAP allows a company to maintain a shared set of contact information. Many companies keep a common LDAP address book for all their employees or for client contacts.</p>

<title>Adding an LDAP address book</title>

<steps>
<item><p>Click <guiseq><gui>File</gui><gui>New</gui><gui>Address Book</gui></guiseq>.</p></item>
<item><p>In the <gui>General</gui> tab, select the type <gui>On LDAP Servers</gui>.</p></item>
<item><p>Enter a name that you prefer.</p></item>
<item><p>Enter the address of the server, the port number (the default number is 389) and whether you want to connect securely.</p></item>
<item><p>Define the login method and your user name.</p></item>
<item><p>Click <gui style="button">Apply</gui>.</p></item>
<item><p>In the <gui>Details</gui> tab you can define the following settings:</p>
<list>
 <item><p>Search Base: The search base is the starting point for a directory search. Contact your system administrator for information about the correct settings.</p></item>
 <item><p>Search Scope: The search scope is the breadth of a given search. The following options are available:</p>
  <list>
  <item><p>One: Searches the Search Base and one entry below it.</p></item>
  <item><p>Sub: Searches the Search Base and all entries below it.</p></item>
  </list>
 </item>
 <item><p>Search Filter: The search filter can be set here for all the LDAP queries. For example:</p>
  <list>
  <item><p><code>ObjectClass=*</code>: Lists all the objects from the server.</p></item>
  <item><p><code>ObjectClass=User</code>: Lists only the users.</p></item>
  <item><p><code>Filter (|(ObjectClass=User)(ObjectClass=groupOfNames))</code>: Retrieves the User and Contact List objects.</p></item>
  <item><p><code>(&amp;(mail=*)(ObjectClass=*))</code>: Lists the objects associated with the email addresses.</p></item>
  </list>
 </item>
 <item><p>Timeout (minutes): The maximum time Evolution attempts to download data from the server before giving up.</p></item>
 <item><p>Download Limit: The maximum number of results for a given search. Most servers refuse to send more than 500 contacts, but you can set the number lower if you want to shorten downloads for very broad searches.</p></item>
</list>
</item>
</steps>

<note><p>If you are unsure about some settings, ask your system administrator.</p></note>

<title>Differences to local address books</title>

<p>LDAP address books work like local address books on your computer, with the following exceptions:</p>
<list>
<item><p>Network folders are only available when you are connected to the network. If you use a laptop or have a modem connection, you might want to copy or cache some of the network directory. You do this by dragging and dropping your desired contacts into the local address books.</p></item>
<item><p>You can also mark the network folder for offline usage. To mark the folder, right-click the folder, click Properties and select Copy Folder Content Locally for Offline Operation.</p></item>
<item><p>Для предотвращения расхода сетевого трафика, Evolution обычно не загружает данные с серверов LDAP во время открытия.</p></item>
<item><p>В зависимости от настроек сервера, вам может быть не доступно редактирование всех полей в контактах, хранящихся на сервере LDAP. Некоторые серверы запрещают частичные или полные изменения, а другие используют меньший набор полей, чем разрешает Evolution. Свяжитесь в вашим системным администратором если вам нужны другие настройки.</p></item>
