+/**
+ * An object to lookup user and group principals by name. A {@link UserPrincipal}
+ * represents an identity that may be used to determine access rights to objects
+ * in a file system. A {@link GroupPrincipal} represents a <em>group identity</em>.
+ * A {@code UserPrincipalLookupService} defines methods to lookup identities by
+ * name or group name (which are typically user or account names). Whether names
+ * and group names are case sensitive or not depends on the implementation.
+ * The exact definition of a group is implementation specific but typically a
+ * group represents an identity created for administrative purposes so as to
+ * determine the access rights for the members of the group. In particular it is
+ * implementation specific if the <em>namespace</em> for names and groups is the
+ * same or is distinct. To ensure consistent and correct behavior across
+ * platforms it is recommended that this API be used as if the namespaces are
+ * distinct. In other words, the {@link #lookupPrincipalByName
+ * lookupPrincipalByName} should be used to lookup users, and {@link
+ * #lookupPrincipalByGroupName lookupPrincipalByGroupName} should be used to
+ * lookup groups.
