credentials are managed by the extension, and do not have to be put into
core-site.xml.
To use MSI, the following two steps are needed:
1. Modify the VM deployment template to specify the port number of the token
service exposed to localhost by the identity extension in the VM.
2. Get your Azure ActiveDirectory Tenant ID:
1. Go to [the portal](https://portal.azure.com)
2. Under services in left nav, look for Azure Active Directory and click on it.
3. Click on Properties
4. Note down the GUID shown under "Directory ID" - this is your AAD tenant ID
To use MSI, modify the VM deployment template to use the identity extension. Note the
port number you specified in the template: this is the port number for the REST endpoint
of the token service exposed to localhost by the identity extension in the VM. The default
recommended port number is 50342 - if the recommended port number is used, then the msi.port
setting below can be omitted in the configuration.
