I have copied a database to my system from a different server. I dont know the user name & password of that database. I tried to connect to the copied database on my system with user SYSDBA & password as masterkey. It gives following error message.

"Your Login SYSDBA is same as one of the SQL role name. Ask your database administrator to setup a valid FireBird Login".

Can anybody help me to connect to this database. How can I proceed.
