Webcalendar configuração.

Pessoal criei o usuario eo bd no mysql e quando tento logar com o webcalwendar aparece essa mensagem,Sera que esta faltando alguma configuração no apache?

# Supported databases for your PHP installation: mysql, postgresql
# Your current database settings are not able to access the database or have not yet been tested.
# Your current database settings are able to access the database.
# HTTP-based authentication was not detected. You will need to reconfigure your web server if you wish to select "Web Server" from the "User Authentication" choices below.

Quando clico no botão teste(webcalendar) aparece isso
Connection Result:
Failure
Reason:
Access denied for user 'admin'@'localhost' (using password: YES)

Agradeço a ajuda
