Trying To Implement ADAL (Azure AD) In Javascript, Keep Getting A Login/redirect Loop

So I've got to create a calendar in html that gets events from Outlook and then deploy that as a custom page to Sharepoint, so it can be included as a webpart/iframe in site collec

Solution 1:

I can reproduce your issue on my side by using your code. If you use authContext.getCachedUser() to check login status, redirect issue will disappear.

if (authContext.getCachedUser()) {
        authContext.acquireToken(config.clientId, function (error, token) {
            if (error) { //acquire token failure
                if (config.popUp) {
                    // If using popup flows
                    authContext.acquireTokenPopup(config.clientId, null, null, function (errorDesc, token, error) { });
                }
                else {
                    // In this case the callback passed in the Authentication request constructor will be called.
                    authContext.acquireTokenRedirect(config.clientId, null, null);
                }
            }
            else {
                //acquired token successfully
                // alert('token success');
                alert(token);
            }
        });
    }
    else {
        // Initiate login
        authContext.login();
    }
