I think I know what is the reason for this - we ask for one Firebird
specific item on connection. The error code is not correct, since that is
not XSQLDA structure, but the rest fits perfectly. Ok, since that item is
important for us, I suspect that IB compatibility will not available in
JayBird 2.0 and higher.

Thanks for the report!
