>                 URL: https://issues.apache.org/jira/browse/IGNITE-8701
>             Project: Ignite
>          Issue Type: Bug
>          Components: jdbc
>    Affects Versions: 2.5
>            Reporter: Ilya Kasnacheev
>            Assignee: Vladimir Ozerov
>            Priority: Critical
>             Fix For: 2.6
> Previously, Ignite JDBC clients would just ignore supplied login and password.
> In 2.5, Ignite Thin JDBC driver will instead fail with following error:
> {code}
> The requested operation could not be performed due to the following error : Handshake
failed [driverProtocolVer=ClientListenerProtocolVersion [major=2, minor=5, maintenance=0],
remoteNodeProtocolVer=ClientListenerProtocolVersion [major=2, minor=5, maintenance=0], err=Handshake
error: Can not perform the operation because the authentication is not enabled for the cluster.]
> {code}
> when connecting to the cluster where authentication is disabled.
> This represents a *breaking change* in Apache Ignite API.
> Note that many tools (such as Informatica) insist on providing non-blank username and-or
password for JDBC connections. This will mean they *no longer work* with Apache Ignite with
no apparent workaround.
> My suggestion is to ignore login/password for JDBC Thin connections when authentication
is not enabled for cluster.
