Choose your authentication model (2.1 only) Firebird 2.1 and higher support three authentication models when connecting to databases account name. On Linux, the mixed model is used. On Windows, the default is mixed in 2.1, 2.1.1 and 2.1.2, and native in 2.1.3 and higher. You can change the model by setting the Authentication parameter operation will be completed successfully. (In pre-2.0 Firebird, this too would cause an error and halt execution.) See also the section below, Expressions involving NULL, about concatenating in expressions involving
