Summary	0037118: The login page allows users to enter only blank spaces in the username field and proceeds instead of validating the input.
Description	When a user enters only blank spaces in the username field and tries to log in with any password, the system does not display any validation error and processes the request. This may lead to unexpected behavior and reduces the overall security and input validation of the application.
Steps To Reproduce	Open the MantisBT website. Navigate to the Login page. Enter blank spaces in the Username field. Enter any password. Click on the Login button. Observe the system behavior.
