HashMapped User Realm. An implementation of UserRealm that stores users and roles in-memory in HashMaps.
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:
username: password [,rolename ...]
Passwords may be clear text, obfuscated or checksummed. The class com.mortbay.Util.Password should be used to generate obfuscated passwords or password checksums. If DIGEST Authentication is used, the password must be in a recoverable format, either plain text or OBF:. The HashUserRealm also implements SSORealm but provides no implementation of SSORealm. Instead setSSORealm may be used to provide a delegate SSORealm implementation.
