No mapping between account names and security IDs was done...

Sometimes you may come across the following error message while deploying cube "No mapping between account names and security IDs was done...". I have answered similar question on msdn forums and the thread for the same is MSDN Thread.

This error comes while deploying cube if one of the active directory user has removed from your active directory but still the reference of that AD user name exist in your SSAS cube Roles.
Connect to Analysis services and go to the "Roles" folder. Open the Role and go to the "Membership" tab, check if "Specify the user and groups for this role" contains any SID (Security Identifier) which looks somewhat like this "S-1-5-21-3623811015-3361044348-30300820-1013". If yes, then remove that and if any such SID is not present then remove and re-add the active directory group and check by doing the deployment.
