Weird Entity Framework error: login failed for user

System.Data.EntityException: "The underlying provider failed on Open." with inner exception: System.Data.SqlClient.SqlException "Login failed for user 'username'" The problem appears to go away if I switch back to using a single giant DbContext. Does anyone know what this means/how to fix it?

Cannot open database, requested by the login. The login ...

Login failed for User is a general sql error message and may have several causes. So, first you have to make sure that the user exist on SQL Server, that the user is enabled, and has access (mapped) to the correct database. In most cases, just set "Integrated Security=False" and it will work.
