This value indicates whether user identification information could be obtained for the associated TCP connection, using noError(1) to mean the information is available or unknownError(2) to mean it is not. An admin checks it before trusting the identUserid and identMisc fields for that connection, since those are only meaningful when identStatus is noError. For example, an identStatus of unknownError(2) tells the admin the remote host did not respond to the ident query, so no username should be expected for that row.
