Assuming you are using Fb 2.5:

1. As SYSDBA, create a user, e.g. ismael
2. As SYSDBA, grant the RDB$ADMIN role to user ismael
3. Log in as ismael, supplying the role 'RDB$ADMIN'

Now, user ismael should succeed in creating another user.

See 1, 2, 3 above. But it won't work if your server is not v.2.5 and your database is not ODS 11.2
