Getting a database login failed message in Crystal Reports? We help troubleshoot ODBC, OLE DB, SQL Server, permissions, DSN settings, driver changes, and saved connection problems.

Crystal Reports login errors usually happen when the report cannot connect to the database using the expected driver, server, user, password, DSN, or permissions.
Many older Crystal Reports use ODBC or OLE DB connections. If a driver, DSN, or server setting changes, the report may stop connecting.
SQL Server reports may fail if permissions, authentication type, database access, or stored procedure rights changed.
