+Exercise 2: Authentication
+This script demonstrates how to authenticate with Zerto API using Keycloak.
+
+Prerequisites:
+1. Install the zvml package in development mode:
+   cd /path/to/zvml-python-sdk
+   pip install -e .
+2. Update prerequisites/config.py with your ZVM details
+
+Your task:
+1. Initialize ZVMLClient with Keycloak credentials
+2. Test connection by retrieving local site information
+3. Handle authentication and connection errors
+
+If you need help, check the solution in the solution directory.
