# URZ: XMPP Client Configuration

This source provides technical instructions for configuring a chat client to connect to the Universität Greifswald XMPP server.

## Key Technical Details

### Recommended Client
The Universitätsrechenzentrum (URZ) recommends the use of **Pidgin**, a free multi-protocol client.

### Connection Parameters
To establish a connection to the university's chat server, the following settings must be used:
- **Protocol**: `XMPP`
- **User**: The user's [[zentraler-nutzeraccount]] (central university username).
- **Domain**: `jabber.uni-greifswald.de`

### Security Validation
The URZ emphasizes the importance of verifying the server certificate to ensure a secure connection. Users can access the Certificate Manager in Pidgin (**Extras -> Zertifikate**) to verify the fingerprint of `jabber.uni-greifswald.de`.

**Valid Certificate Data (as of source date):**
- **Common Name**: `jabber.uni-greifswald.de`
