Use shared address books on a local network.

# Adding LDAP access

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.

# Adding an LDAP address book

Click File New Address Book.

In the General tab, select the type On LDAP Servers.

Enter a name that you prefer.

Enter the address of the server, the port number (the default number is 389) and whether you want to connect securely.

Define the login method and your user name.

Click Apply.

In the Details tab you can define the following settings:

Search Base: The search base is the starting point for a directory search. Contact your system administrator for information about the correct settings.

Search Scope: The search scope is the breadth of a given search. The following options are available:

One: Searches the Search Base and one entry below it.

Sub: Searches the Search Base and all entries below it.

Search Filter: The search filter can be set here for all the LDAP queries. For example:

`ObjectClass=*`: Lists all the objects from the server.

`ObjectClass=User`: Lists only the users.

`Filter (|(ObjectClass=User)(ObjectClass=groupOfNames))`: Retrieves the User and Contact List objects.

`(&(mail=*)(ObjectClass=*))`: Lists the objects associated with the email addresses.

Timeout (minutes): The maximum time Evolution attempts to download data from the server before giving up.

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.

If you are unsure about some settings, ask your system administrator.

# Differences to local address books

LDAP address books work like local address books on your computer, with the following exceptions:

网络文件夹仅当您连上网络之后才能操作。如果您使用的是笔记本电脑或使用调制解调器连接，可能想要复制或缓冲网络文件夹的一部分内容。您可以将里面需要的联系人条目拖拽到本地地址簿里。

您也可以标记网络文件夹供离线使用。要标记该文件夹，右键点击文件夹，选择”属性“，选择”复制文件夹内容到本地供离线操作“。

To prevent excess network traffic, Evolution does not normally load data from the LDAP server upon opening.

Depending on your server settings, you might not be able to edit all the fields in a contact stored on an LDAP server. Some servers prohibit some or all changes, and others use a smaller set of fields than Evolution allows. Check with your system administrator if you need different settings.
