I do it like this, it's been in use for several months and for me it
works perfectly under Openldap/SSL, tested from 2.1.3 up to 2.1.6:

objectClass: top
objectClass: person
objectClass: organizationalPerson
objectClass: inetOrgPerson
objectClass: evolutionPerson <--- Ximian's Evolution
objectClass: posixAccount
objectClass: shadowAccount
objectClass: inetLocalMailRecipient

Under ROUTERS:

mail_redirect:
  driver = redirect
  allow_fail
  allow_defer
  data  = ${lookup ldapm {ldaps://localhost/\
    dc=billy,dc=demon,dc=nl?mailRoutingAddress?sub?\
    (&(objectClass=inetlocalMailRecipient)(uid=$local_part))\
    }\
    {$value} fail }
# user = exim
  file_transport = address_file
  pipe_transport = address_pipe



It's called "mail_redirect", since it also redirects mail for users who
have their accounts on other machines / in other mail domains. I have a
separate router for Lachmann-Laser based system aliases, which works
more or less the same and comes after this one.

Above it I have this comment:

## This router handles ldap-based aliases
#
# Obviously ldap has to be configured and running before it will work.
# Make sure that it comes before any local routers, including
# Spamassassin,
# since subseqent to these it will use the standard /etc/ldap.conf
# filter
# and it expressly uses its own filter *before* the standard filter is
# called.

Success,

Tony
