Camille Fournier commented on ZOOKEEPER-1759:
---------------------------------------------
Oh yes, I checked this in but I agree with that. Also do we need documentation
somewhere about this new property?
> Adding ability to allow READ operations for authenticated users, versus
> keeping ACLs wide open for READ

> Today when using SASLAuthenticationProvider to authenticate Zookeeper Clients
> access to the data based on ACLS set on znodes there is no other choice but
> to set READ ACLs to be "world", "anyone" with the way how
> {code:java}
> public boolean matches(String id,String aclExpr)
> {code}
> is currently implemented. It means that any unauthenticated user can read the
> data when application needs to make sure that not only creator of a znode can
> read the content.
> Proposal is to introduce new property: "zookeeper.readUser" that if incoming
> id matches to the value of that property it will be allowed to proceed in
> "match" method.
> So creator of a znode instead of
> {code:java}
> ACL acl1 = new ACL(Perms.ADMIN | Perms.CREATE | Perms.WRITE | Perms.DELETE,
> Ids.AUTH_IDS);
> ACL acl2 = new ACL(Perms.READ, Ids.ANYONE_ID_UNSAFE);
> {code}
> will need to do
> {code:java}
> ACL acl1 = new ACL(Perms.ADMIN | Perms.CREATE | Perms.WRITE | Perms.DELETE,
> Ids.AUTH_IDS);
> ACL acl2 = new ACL(Perms.READ, new Id("sasl", "anyone"));
> {code}
> Assuming that value of "zookeeper.readUser" property was "anyone".
> This way at least READ access on corresponding znode has to be authenticated.
