Javascript API ArcGIS Online sign in error

[LukeStewart]

I am developing an application and trying to use the Portal tools now built into the JS API. I have managed to get it searching ArcGIS Online items and add them to the map but am having issues trying to sign into my organisational account to view private items. I am using the code from the samples (below) to try and sign in. It worked a couple of times but I can now not get it to sign in and have made no changes to the code that would break it. I get the error in the attached image in firebug.
Can anyone shed any light on this?

function signIn() {
var signInLink = dojo.byId('signIn');
if (signInLink.innerHTML.indexOf('In') !== -1) {
portal.signIn().then(function (loggedInUser) {
signInLink.innerHTML = "Sign Out";
}, function (error) {
signInLink.innerHTML = 'Sign In'; //error so reset sign in link
});
} else {
portal.signOut().then(function (portalInfo) {
signInLink.innerHTML = "Sign In";
});
}
}

Luke,

signIn uses the Identity Manager to allow users to enter their credentials. The IdentityManager requires SSL because we don't want to send credentials via non-SSL channels.

If you are in a development/testing machine that doesn't have a valid SSL certificate you can override the restriction using something like the code below to test the sign-in process. Just remember to remove this code before moving to a production environment.

    dojo.addOnLoad(function() {
      esri.config.defaults.io.proxyUrl = proxyUrl;
 
      esri.id.setProtocolErrorHandler(function() {
                // return true from this handler if you want to proceed anyway
                // with the protocol mismatch
                return window.confirm("This application is going to send your credentials across a non secure protocal.  Proceed?");
     
              });
    });

Hi,

It is a development environment but I am running it through HTTPS on my IIS. I have also tried the work around you provided and it is still not working.

The error in FireBug is telling me XMLHttpRequest cannot load..... https://127.0.0.1 is not allowed by Access-Control-Allow-Origin.

Then 3:

TypeErrors

It is some kind of security issue and I do not know very much about this area. Is there anything else you can suggest that may help to get this working??

Thanks

I finally figured this one out. In the end it has nothing to do with SSL or permissions and everything to do with ####.

I had <a href="#"  tags in my JS and when clicking on links with this syntx a # was added to the end of the main url e.g something/something.html#. This # was subsequently causing the ArcGIS Online login to fail.

I have now removed all the #'s and the login is working fine. Of course this has meant some other parts of the application do not work in certain browsers but that is another story.
