When trying to connect to Firebird 3 using NON sysdba (legacy user) error "Your user name and password are not defined. Ask your database administrator to set up a Firebird login." i s returned.
Test against Firebird 3 configured as:
AuthServer = Legacy_Auth, Srp
AuthClient = Legacy_Auth, Srp
UserManager = Legacy_UserManager, Srp
WireCrypt = Enabled
ServerMode = Classic
Tried on 2 users:
CREATE USER USR_LEG PASSWORD 'PASLEG11' USING PLUGIN Legacy_UserManager;
CREATE USER USR_SRP PASSWORD 'PASSRP22' USING PLUGIN Srp;
User USR_LEG is working with FirebirdClient 4.10 and below
User USR_SRP is working with FirebirdClient 5.10 and above.
Both users is working using ISQL and IBexpert.
