Hi,
We're having severe performance issues for any query with alias dereferencing set to "always".
Any query with this causes the CPU to spin up to 100% and if we have a number of these concurrently the machine will become unresponsive.
We're using OpenLDAP 2.4.42 with the old hdb backend.
We do have a large number of aliases (~63,000). Could this be the cause?
Our olcMaxDerefDepth is currently set to "1"
