[exim] LDAP query help

I'm hoping for some help in getting this right

I'm using ldap to query Active Directory as per this recommendation

http://www.exim.org/mail-archives/exim-users/Week-of-Mon-20040816/msg00126.html

when exim -d+deliver -v -bt dmacphXXX@???

I get:

ldap_parse_result yielded 34: Invalid DN syntax
lookup failure forced
LDAP search failed - error 34: Invalid DN syntax/0000208F: LdapErr:
DSID-0C090654, comment: Error processing name, data 0, vece


this might be helpful from the debug, i can send the whole debug info if
needed

perform_ldap_search: ldap URL =
"ldap:///"dc=mfe,dc=ca"?mail?sub?(&(|(objectClass=user)(objectClass=publicFolder)(objectClass=group))(proxyAddresses=SMTP:dmacpherson%40mainframe.ca))" server=172.16.132.71 port=0 sizelimit=0 timelimit=0 tcplimit=0
