Does exist any way to read the acl by sid, instead of:
Code:
	ObjectIdentity oid = new ObjectIdentityImpl(object, id);

		List<AccessControlEntry> listAce = mutableAclService.readAclById(oid)
				.getEntries();
I want to read the acl wy user, with something like this: readAclBySid(id)

Is it possible?
