FILE: identity_sample_async.py
DESCRIPTION:
These async samples demonstrate creating a user, issuing a token, revoking a token and deleting a user.
USAGE:
python identity_samples_async.py
Set the environment variables with your own values before running the sample:
1) AZURE_COMMUNICATION_SERVICE_ENDPOINT - Communication Service endpoint url
2) COMMUNICATION_AUTH_SAMPLES_CONNECTION_STRING - the connection string in your Communication Services resource
3) AZURE_CLIENT_ID - the client ID of your active directory application
4) AZURE_CLIENT_SECRET - the secret of your active directory application
5) AZURE_TENANT_ID - the tenant ID of your active directory application
6) COMMUNICATION_M365_APP_ID - the application id of Microsoft 365
7) COMMUNICATION_M365_AAD_AUTHORITY - the Azure AD authority of M365
8) COMMUNICATION_M365_AAD_TENANT - the tenant ID of Microsoft 365 application
9) COMMUNICATION_MSAL_USERNAME - the username for authenticating via the MSAL library
10) COMMUNICATION_MSAL_PASSWORD - the password for authenticating via the MSAL library
