Hello,

I try to configure a proxy-server with back_meta connecting to to different AD-domains. I'm getting the result as expected if I do an ldapsearch. But now I want to add caching for the data, so I configured the following: ---------------- dn: cn=config objectClass: olcGlobal cn: config olcArgsFile: /var/symas/run/slapd.args olcLogLevel: any olcPidFile: /var/symas/run/slapd.pid olcToolThreads: 1

----------------

The same pcache setup works with back_ldap.

What did I do wrong or did I miss something.

Using this setting with back_ldap, doing a ledapsearch, stopping the domaincontroller, repeat the ldapserch, because the data is in cache I still get the result. Seting up back_meta, as soon as I stop the domaincontroller I got nothing at all.

Do I have to set up a cache for every uri? Then what should be the DN?
