Trying to create/restore a backup in Firebird 3. failing miserably.

I get:

no permission for CREATE access to DATABASE

  IBORestoreService.Params.Add('user_name=MYUSER');

  IBORestoreService.Params.Add('password=MYPASSWORD');

  IBORestoreService.Params.Add('sql_role_name=RDB$ADMIN');

Any Idea why?

This works via command line though:

"D:\Program Files (x86)\Firebird\Firebird_3_0\gbak.exe" -C D:\Testsystems\Customer\data\op.fbk D:\Testsystems\Customer\data\op.fdb -role RDB$ADMIN

Kind Regards,

Robert Gilland.
