it won’t work if you truncate it to the first 20 characters! Legacy authentication The installer does not offer an option to enable legacy authentication. You will need to configure this manually if should be), you should not use the Legacy_Auth authentication plugin or enable it only temporarily while you upgrade your existing clients to Firebird 5.0. The legacy connection method sends passwords 0.n with your version number, e.g. 5.0.0 or 5.0.1 If you’re running applications that expect the legacy libraries to be present, also create the following symlinks: Chapter 3.

Three dialects are available: • Dialect 1 is intended solely to allow backward comptibility with legacy databases from very old InterBase versions, v.5 and below. Dialect 1 databases retain certain language and cannot be set in the database. It is intended to assist debugging of possible problems with legacy data when migrating a database from dialect 1 to 3. • In Dialect 3 databases, ◦ numbers (DECIMAL generator in Firebird and its ancestor, InterBase. The NEXT VALUE FOR operator is equivalent to the legacy GEN_ID (…, increment) function with increment the increment stored in the metadata of the sequence
