During access logging, the system identifies:

  • Directory users by their authcid, the logon username by which the directory authenticates the user, which the system stores in DBC.SessionTbl.AuditTrailId when it establishes the session.
  • Proxy users by the name by which they are initially authenticated when accessing the middle tier application. The access log includes a copy of the query band string for the proxy user.
