Sendmail 8.10.0 vs. LDAP

[Les Barstow <lbarstow@vr1.com>]

Arrgghh!!!

I've been fighting with Sendmail 8.10.0 for the past several days to
implement an alias map using LDAP, and have been very unsuccessful.
I'm looking for some help.

I have set up my alias lists as rfc822MailGroup objects, with
rfc822Mailbox entries for each individual, and cn=aliasname for the
RDN.  I have the following set up in my .cf file:

O LDAPDefaultSpec=-hldap.vr1.com -b"ou=Aliases,dc=vr1,dc=com"
Kldapaliases ldap -k"cn=%s" -vrfc822Mailbox -z,
O AliasFile=sequence:ldapaliases

(The AliasFile sequence bit is a leftover from the ldapx map problem)

This all looks well and good, but when I try to do a lookup, I get
the following:

421 4.0.0 Error getting LDAP entries in map ldapaliases: Decoding error

If I remove the '-z,' (which is supposed to tag multi-valued responses
together into an alias list), I get the first value in the list (as is
to be expected).

So: it appears my LDAP map is correct, and Sendmail can connect to the
    LDAP server, but it does not know how to do multi-valued lists
    (this was supposed to be one of its new features...)

Any recommendations on how to fix the Sendmail side?  The
comp.mail.sendmail group hasn't come back with a response...

Should I go to mail500?  If so, will it do local delivery?  This is a
smaller setup, so users and aliases are not distinguishable by mail
host (hub vs. end-server).  Does anyone have a set of sendmail rules
which do appropriate map lookups for this?
