🐛 Describe the bug

Recently we implemented the MWAA COgnito login as explained in the following sites.

• Application load balancer single-sign-on for Amazon MWAA
• Accessing a private Amazon MWAA environment using federated identities

When I accessed this ALB and Lambda Based Cognito login to MWAA Airflow UI, it creates a new user in Airflow list of users every time.

🕵️ Expected behavior

I expected a unique Cognito user should create only one user entry in Airflow.

📜 To Reproduce

1. Access the MWAA Airflow UI using the new ALB based approach multiple times using same Cognito user
2. Check the list of users in Airflow UI - Security Menu
3. Observe that it is creating a new user everytime you logged in with same Cognito user

A user name was automatically generated as a UUID which is why many users were created.
Ramesh fixed that by using the actual user name.
