Hi All,

I am trying to login to sandbox from Force.com IDE. I am getting the following error:

Unable to connect to hostname 'test.salesforce.com':
Invalid username, password, security token; or user locked out.
Please verify and/or change your credentials

When I entered Force.com IDE, I selected the environment "Sandbox" and gave the required credentials.

I could able to login from www.salesforce.com.

Coul anyone please help me to fix this? Your help is greatly appreciated.
