Deshalb, um ID-Kollisionen zu vermeiden, könnten Sie beim Erstellen des JWT-Tokens für den Benutzer, dem Wert des `sub`-Schlüssels ein Präfix, z. B. `username:` voranstellen. In diesem Beispiel hätte der Wert von `sub` also auch `username:johndoe` sein können.

Der wesentliche Punkt ist, dass der `sub`-Schlüssel in der gesamten Anwendung eine eindeutige Kennung haben sollte, und er sollte ein String sein.

## Changes

 * SMB2 (2.02 protocol level) support, some SMB3 support
 * Remove global state
 * Allow per context configuration
 * Logging through SLF4J
 * Drop pre-java 1.7 support
 * Unify authentication subsystem, NTLMSSP/Kerberos support
 * Large ReadX/WriteX support

 * 
 * Usually you will want to create one context per client configuration and then
 * multiple sub-contexts using different credentials (if necessary).
 * 
 * {@link #withDefaultCredentials()}, {@link #withAnonymousCredentials()}, {@link #withCredentials(Credentials)}
 * allow to create such sub-contexts.
 * 
 * 
 * Implementors of this interface should extend {@link jcifs.context.BaseContext} or
