I have a ACL enabled game.I wanted to test my facebook login feature. What I am doing now with facebook is that: when user link his facebook account, I save his fbUserId to user's data table which includes his username etc. Then, next time when he clicks login with facebook button, I get username whose fbUserId equals current user id. Then, on server side I use GetSession(create) api using this username and login to game. After I login, I can use storage service etc but while I am trying to use buddy service, it fires 1401 error. What is the problem here? I created session for the user and everything should be fine!
