Database error log shows "*****" instead of username on connection error

Hi,

I get a very strange message for a failed connection to a MariaDB 10.2.31 database. The connection comes from an application (Manticore) using libmysqlclient.so.18

This is the error message: 2020-04-27 15:54:24 139657574090496 [Warning] Access denied for user '**'@'localhost' (using password: YES)

I tried with using the same credentials from a terminal with mysql and all is good.

I tried using a wrong password from a terminal and the error message shows the user name correctly.

Now the question is: what would trigger the error reporting to displaying "**" instead of the user name ?

Or is it exactly this string that is passed on the connection DSN by the client ?

Is there any way to debug this ?

Thanks Roberto
