How to automate JAAS authentication

I am using JAAS form-based authentication to prevent unauthorized page access. Once logged in the user's roles remain in effect untilt he session expires. Users are demanding a "remember me" check box. That requires programmatic login in addition to, not in place of, the form-based intercept. What is the API call to authenticate a user? Googled my brains out but no solutions appeared. .
