/**
* Properties User Realm.
* <p>
* An implementation of UserRealm that stores users and roles in-memory in HashMaps.
* <p>
* Typically these maps are populated by calling the load() method or passing a properties resource to the constructor. The format of the properties file is:
*
* <pre>
* username: password [,rolename ...]
* </pre>
*
* Passwords may be clear text, obfuscated or checksummed. The class com.eclipse.Util.Password should be used to generate obfuscated passwords or password
* checksums.
* <p>
* If DIGEST Authentication is used, the password must be in a recoverable format, either plain text or OBF:.
