this is the schema and this table is created I the user database
[SPID] [int] NULL,
[LoginName] [varchar](512) NULL,
[HostName] [varchar](512) NULL,
[HostID] [int] NULL,
[LoginTime] [datetime] NULL,
[ApplicationName] [varchar](512) NULL,
[DatabaseName] [varchar] (10)
which login should I give insert permission to this table and why it is blocking all user's to log into the database
