I need a way to auto login our users to another site that we have an account with and have setup accounts for our users under our master. I know the password and user id (our users don't know them as they are required to login to our site first and then be passed over to this other site. No they don't have an api and yes we have permission to do so).
What other options do i have to do this? I've looked at curl and there's the whole cookies issue and have not been able to get it to work.
