openldap 2.3 latest
the dynlist feature works when I change the database backend from ldap to a bdb backend replica of the master. That's unfortunate, I'd like to not have to replicate the data to my local ldap box.
slapo-dynlist(5) works as expected (in 2.4) with slapd-ldap(5) as the backend serving the "DN" portion of the "memberURL". I suspect in your case the issue is related to issues like ACL, identity and similar things. You should check whether the remote server is actually contacted and how the operation is served in general. Looking at the logs (on both servers) with increasing level of verbosity, from "stats" to "stats,trace,args" would help.
