rwm-mapping problem

["Wanek, Daniel J." <dwanek@state.nd.us>]

I am setting up a OpenLDAP front-end proxy that allows limited access to
an Active Directory target server and am a little stumped on an issue
that keeps causing an Abort to the OpenLDAP proxy.  Any time a search
filter is sent through that is mapped to nothing the server will abort.
Here are my mappings:

overlay rwm
rwm-map objectclass  account user
rwm-map attribute    uid     sAMAccountname
rwm-map attribute    cn      name
rwm-map attribute    sn      sn
rwm-map attribute    mail    mail
rwm-map attribute    ou      company
rwm-map attribute    entry   entry
rwm-map attribute    *

So if I specify a search query that I DON"T want users to access such as
(telephoneNumber=8888*) the OpenLDAP server will abort with the
following:

slapd: result.c:538: slap_send_ldap_result: Assertion
`!((rs->sr_err)<0)' failed.
Aborted

If I add the attribute that is breaking the server to the rwm-map list,
like the following, it works fine but I don't want users to have access
to that attribute, so I'm a little stuck.
rwm-map attribute    telephoneNumber  telephoneNumber
 
Any advice would be appreciated.

BTW, I'm using OpenLDAP version 2.3.9 on Debian Linux
