[Bug 1949565] Re: Cannot connect anymore to Azure Database for MySQL with 8.0.27-0ubuntu0.20.04

2021-11-13 Thread Olivier Le Pogam
Hi Utkarsh !

Quite simple, but unfortunately an Azure Environment is required to reproduce 
it ...
- A simple VM with Ubuntu 20.04
- An instance of Azure Database for MySQL (which is actually a PaaS MySQL) : 
https://azure.microsoft.com/en-us/pricing/details/mysql/server/

Latest mysql-8.0 libraries

Then simply try to connect with "mysql" command line to the Azure
Database for MySQL => you'll be stuck.

If you don't have such en environment, I can open a free trial one,
create a VM & an Azure Database for MySQL Service, and we can work on it
together.

Best regards

[Bug 1949565] [NEW] Cannot connect anymore to Azure Database for MySQL with 8.0.27-0ubuntu0.20.04

2021-11-03 Thread Olivier Le Pogam
Public bug reported:

Hello,

When I upgrade my Ubuntu 20.04 VM with with mysql-8.0 version
8.0.27-0ubuntu0.20.04, the connection to any of my Azure Database for
MySQL is frozen (no timeout, but no response) using the mysql CLI.

Downgrading to 8.0.19 fixes the issue.

Of course, there is no network related issue (since 8.0.19 works fine).

Are the security enhancements the cause of this issue ? Sounds like the
authentication negociation is failing and is stuck somewhere ...

Weird thing is the "no response" behavior, instead of having an error
returned.

Best regards
