# Thunderbird Central Address Book Configuration

This entity describes the specific technical configuration required to link [[mozilla-thunderbird]] to the [[zentrales-adressbuch]] provided by the [[universitatsrechenzentrum-urz]].

## Setup Procedure
1. Navigate to **Settings (Preferences)** $\rightarrow$ **Composition** $\rightarrow$ **Addressing**.
2. Enable the **LDAP Directory Server** option.
3. Click **Edit** and use the **Add** button to create a new server entry.

## Connection Parameters
The following parameters must be used to establish a connection to the university's LDAP server:

| Parameter | Value |
| :--- | :--- |
| **Server Name** | `adressbuch.uni-greifswald.de` |
| **Port** | `636` |
| **Protocol Version** | `LDAP v3` |
| **Encryption** | TLS/SSL (AES 256+) |
| **Base DN** | `dc=uni-greifswald,dc=de,dc=TLD` |

## Critical Post-Configuration Step
After setting up the server, users must perform [[primary-email-attribute-mapping]] to ensure the client uses the `UniHGW-PrimaryEmailAddress` attribute instead of the default `mail` attribute. This requires a restart of the application.
