Set Up Multi-User Mode

This guide connects ELN3 to your MySQL server and WebDAV storage. You should have both ready before starting — see Install MySQL and Set Up WebDAV.

Prerequisites

Step 1: Run the Connection Wizard

1. Launch ELN3 — the Connection Wizard opens automatically on first run
2. Select Remote connection mode
3. Enter your MySQL settings:

4. Enter your WebDAV settings:

5. Click Test Connection — the wizard verifies MySQL connectivity, database access, and WebDAV availability
6. If all checks pass, click Connect

Tip: If the connection test fails, a diagnostics dialog will pinpoint exactly which step is failing (DNS, port, credentials, database). Fix the reported issue and retry.

Step 2: Create the Admin User

After connecting, ELN3 prompts you to create the first user:

1. Enter First Name, Last Name, Login, Email
2. Set a strong password
3. The role is automatically set to Admin
4. Click Save

This is your administrator account with full system access.

Step 3: Verify the Setup

After logging in as Admin:

1. Check the status bar at the bottom — it should show the MySQL connection and server address
2. Open Users > Users Editor — your admin account should be listed
3. Try creating a test project and attaching a file — the file should upload to WebDAV

Connection Diagnostics

If ELN3 can’t connect at startup, the Connection Diagnostics dialog appears automatically. It tests each component:

• DNS resolution — can the server hostname be resolved?
• TCP port — is port 3306 reachable?
• MySQL credentials — are the username and password correct?
• Database existence — does eln3db exist?
• WebDAV access — is the WebDAV server reachable?

From the diagnostics dialog you can Retry, Reconfigure (re-run the wizard), or Exit.

Reconfigure an Existing Installation

To change connection settings on an already-configured workstation:

1. Go to Database > Reconfigure Connection…
2. The Connection Wizard reopens with current settings pre-filled
3. Make your changes and test the connection
4. Restart ELN3 for changes to take effect
