Steps to reproduce:
1. Create user "bob" with password: "adminpwd" and authentication db: "admin"
2. Create user "bob" with password: "pwd" and authentication db: "anyOtherDb"
3. Try to login with the second user using java driver (higher than 4.0.6)  - result is failure (see attachment issue 1.png)
4. Try to login with the second user using java driver (4.0.6) - result is success (see attachment issue 2.png)

Additional notes:
If there is only one user "bob" (second) in system - authentication is successful for all java drivers.
