should sssvlv and translucent overlays work together?

[Steve Eckmann]

I am applying the sssvlv overlay globally and applying the translucent overlay 
to an ldap backend. If I execute a search like:
    ldapsearch -x -H ldaps://localhost -LLL -b dc=example,dc=com \
        -D "cn=admin,dc=example,dc=com" -w admin \
        -E 'sss=cn:2.5.13.3' \
        '(filter)' cn mail localAttr1 localAttr2

the result is sorted by cn, as desired, but the 'cn' and 'mail' attributes are 
not included in the ldapsearch output for proxied entries. It doesn't matter 
whether the filter refers to proxied or local attributes, or some combination. 
I'm not seeing any clues in the slapd debug output (-d -1). In the ldapsearch 
debug output it looks like the proxied attributes are not being returned from 
slapd.

So should the sssvlv and translucent overlays work together, and if so, where 
should I be looking for a misconfiguration?

Thanks.

Steve
