I successfully did that. Just add Legacy_Auth to firebird.conf:

AuthClient = Srp, Srp256, Win_Sspi, Legacy_Auth #Windows clients

Hi,
are you using fresh Zeos from SVN/GH? Is your issue fixed following this report viewtopic.php?f=50&t=167308 ?

From what you discovered, I suspect the buffer is being accessed when it's actually empty because of empty dataset

This is the bug indeed, though calling functions should never use a value when Len is 0 - but we live in a non-ideal world so additional check wouldn't hurt.
Created PR with your fix

I took a glance on StrToBoolEx and was surprised to find plenty of unit tests. How that serious bug with "+1" could even pass the tests?

Seems like good thing to add to test suite

Umm, I don't know precisely but it should be only the matter of proper client lib configuration. Zeos has nothing to do with transport layer. Have you read corresponding MySQL docs?

BTW, I have 2000 and 2005 installed and I can check if 6.5's backup is restorable by these versions. Just provide some dummy test backup

No, the described case is surprise for me, I'm just saying that for DBGrid it's normal to have dataset cursor and focused cell indicator non-synced

Yeah, pretty hard task. Recently I was surfing the web searching for versions > 2000 and found express 2005 at last but that was not easy. But you can stop at 2000 as it has SQL data export already.
Btw, have you tried DB managers like DBeaver? Probably it could connect to 6.5 and do export

Nope. It's the dumbest feature of vanilla dbgrid IMHO and it lasts from the very beginning.

Likely MSVC Runtime dependency in libmysql... General approach to solving issues: 1. Develop the link graph of all the components involved 2. Remove nodes one by one until only one remains (that will be the reason) or the issue is gone (the node you've just removed will be the reason) Here the graph...

This version MSSQL Enterprise Manager does not generate SQL Script for data, only meta. You mean, 6.5? You can try installing a bit more fresh version like 2000 and do backup/restore to it. Then export data as SQL. Old SQL server versions still can be found on Internet. And you always can write you...

Why not export data as good old plain SQL script?
