             Summary: Remote client authentication failed for the CommandHandler in the case where it optional on the server
                 Key: IGNITE-11346
                 URL: https://issues.apache.org/jira/browse/IGNITE-11346
             Project: Ignite
          Issue Type: Bug
          Components: clients, security, thin client
    Affects Versions: 2.7
            Reporter: Maxim Karavaev


h2. Preposition:

Custom _GridSecurityProcessor_ implementation allows optional authentication. With other words, if some credentials are presents then authentication performed, otherwise - not (some restricted SecurityContext returned). 

REST API works fine. If credentials are present or the auth request was made then the auth works as desired, if not - it also works but only for some authorized requests.
h2. The problem:

_CommandHandler_ which is used for controlling a cluster through the CLI script _command.sh|bat_ doesn't respect credential parameters and sends auth request only in case of authentication exception for a regular request. In the described case of optional authentication it never happens, so the result always depends on the "default" Permissions.
h2. Possible solution:

Change _GridClientNioTcpConnection_ to always send first an auth request in case of provided credentials.
