long id here

I have window service which is running on the production server.The
service hit the database server frequently for processing the record.Each
day once it throw below error
Login failed for user 'S-1-5-21-1482476501-1214440339-839522115-500' Msg
18456, Level 14, State 1.
I wondering why it is showing long user name rather the sql username in
the exception.The Server server version 2012.
