I'm trying to authenticate using AAL for Windows Store version 0.61 and get the following error from AcquireTokenAsync:-
Error: authentication_failed
Error Description: Value was either too large or too small for a UInt32.
(I also have a WPF app using ADAL 1.02 which happily authenticates with my Azure tenant so I know the Azure side of things is fine and I'm using the same tenant, resource, clientId, etc. for the store app)
The first time I tried this last night it worked. Today it doesn't!
I suspected the problem might be the TokenCache and have attempted to remove any tokens by calling
AuthenticationContext.TokenCache.Remove(newTokenCacheKey(_authority, _resource, _clientId));
but still get the error. I'm targeting Windows 8.1.
Any suggestions?
Thanks
Michael.
