when used with local authentication, I would have advised to use a stable upload.<br>
<br>
But considering the silent configuration update (which might surprise<br>
people, especially in stable) and the fact we don't really know how<br>
administrators might use user attributes to handle authorizations, it<br>
might makes sense to release a DSA, in order to have more exposure.<br>

OpenLDAP team, what do you think? I can also request a CVE on oss-sec,<br>
so we have a broader idea of what security people think about this.<br></blockquote><div><br></div><div>I don't see any response from the OpenLDAP team yet :-(.<br></div><div><br></div><div><br></div><div>It is perhaps worth noting that the official OpenLDAP documentation has the same issue.</div><div><br></div><div><<a href="http://www.openldap.org/doc/admin24/access-control.html#Basic">http://www.openldap.org/doc/admin24/access-control.html#Basic</a> ACLs></div><div><br></div><div>Has "Generally one should start with some basic ACLs such as:" and the example includes "access to * by self write"</div><div><br></div><div><br></div><div>People I have talked to locally have immediately asked me "where is the CVE?" so I think a CVE would be a good idea.
