I have this problem, I want to setup security on my server for arcgis android app use. I enabled security in arcgis manager, chose to use windows domain users. When i connect on arcgis app to my connection, login request appears, and i successfully login using my windows account. Under Maps i see all my maps, but when i try to load one of them error : "Map has failed to load". When security is disabled- maps load fine. Been reading all over the places, and cant find the answer.
