Hello,
I have an Issue with the ProxyCache on OpenLDAP (2.4.23-32.el6_4.1)[CentOS 6] which should Cache the Queryanswers from an OpenLDAP ( 2.3.43-12.el5_7.9)[CentOS 5] Server.
The Problem isn't the Proxy but the Cache. When I do a query, i get the right Answer. But if I look into the LDAP.log with locklevel=2048, I always get the Strings:
QUERY NOT ANSWERABLE QUERY NOT CACHABLE
and if I shutdown the Server where the Proxy get its Informations it doesn't answers to the same query.
My Konfiguration:
