Problem in adding user in security page in Analysis Service

Recently we had a problem for adding users in Analysis service security option






But we got error while adding user


The following system error occurred:No mapping between account name and security IDs was done.



So we could not add or remove any user in analysis service.

 The error was there is user ID  S-1-5-21-3915353168-1605177054-2951684922-2242

 which is not in Domain or USERS. So it was failing for validation for it.
 So we removed S-1-5-21-3915353168-1605177054-2951684922-2242
it then successfully able to add user in security page.
