Getting {"error": "invalid_grant", "error_description": "failure failure"} in Salesforce?

Question

I am trying to get a session id for a partial Salesforce package.

My code is:

curl https://test.salesforce.com/services/oauth2/token -d "grant_type=password" -d "client_id=definitely the correct client id" -d "client_secret=definitely the correct client secret" -d "username=[e-mail]" -d "password=passandsecuritytoken"

What else have I done:

• Grant full access in the settings of the connected application
• Set ip limits to limit ip limits
• "All users can authenticate themselves"
• Double verified pass, client identifier, client secret, username

I am still getting the error {"error":"invalid_grant","error_description":"authentication failure"}.

I searched the SF forums and StackOverflow questions, but I could not find a solution for this. Does anyone know what else could be the problem here?
