As noted in
http://www.openldap.org/lists/openldap-technical/201004/msg00247.htmlsetting up a chain overlay on the frontend and then configuring ppolicy with ppolicy_forward_updates causes BIND operations with invalid credentials to return success, apparently from the result of the chain operation.
This is independent of the value of chain-return-error.
WHOAMI reports anonymous after these "successful" BINDs with invalid passwords, so there is no security compromise within the directory itself, however this has (as noted in the above email) catastrophic results for external apps trying to authenticate with BIND.
This was already fixed in HEAD by back-ldap/chain.c rev 1.77 (apparently fixed for unrelated reasons).
