/**
* Implementation of {@link UserDetailsService} that dispatches lookups to a backing {@link SecurityPrincipalService}.
* A lookup by username will loop through all active user directories ({@link UserDirectoryService#getActiveUserDirectories()}
* and build a unique principal name for that particular directory. The first non-null {@link UserDetails} implementation
* returned from the {@link SecurityPrincipalService} will be returned.
*
* In case of several directories this lookup will incur a performance hit, adequate caching is advised.
