> *Problem*
> When user access secondary file system, we propagate it form client machine to Ignite server and then try to perform the request on this user using either "doAs" or proxies in case of Kerberos.
> The problem is that user name is not always match what we need. For example, user name is "ivanov", but the request should be performed using proxied user "ivanov@[REALM_NAME]". 
> *Solution*
> We need to introduce special converter interface which will intercept user names and convert them to correct form if needed. This interceptor should be places inside file system factory.
