connection impossible (Connection using old (pre-4.1.1) authentication protocol)

Hi,
since HeidiSQL 9.0 i can't connect to our Server.

Error Message:
Connection using old (pre-4.1.1) authentication protocol refused (client option 'secure_auth' enabled)

How can i disable 'secure_auth' in HeidiSQL ?

Exactly the same error here, updated to v9 and now I can't connect to any of my DBs.

Please can you fix this or at least let me know how to disable the setting as per Richard's request above.

Thanks...Buzz

Just seen the release thread, I'll give the older version of libmysql a go.

Confirmed working with the older 64 bit version of libmysql

See the v9.0 release thread. I will try to activate that secure_auth option, perhaps with a new checkbox in the "Advanced" tab of the session manager.
