Exim doesn't require any attributes in particular - it's pretty
generic. You specify within your queries what attributes to look for or
return.

You wouldn't have to really do anything "in ldap" other than setup the
entries you want. The exim configuration would control what gets
accepted and when to check ldap for forwarding and such.

Assuming your LDAP entries had "mail" attributes, and the forwarding
info was in an attribute named "mailforwardingaddress" (the way Netscape
Directory server is setup), something like:
cn=Bob Smith, o=Foo, c=US
mail: bob@???
mailforwardingaddress: bsmith@???
you could put something like this in as an Exim director:
-----------
ldap_forward:
driver = aliasfile
domains = foo.com
search_type = ldap
query = "ldap:///o=Foo, \
c=US?mailforwardingaddress?sub?(mail=$local_part@$domain)"
-----------
Then mail addressed to bob@??? would be forwarded to bsmith@???
instead. (This is also assuming you have "local_domains = foo.com" and
"ldap_default_servers = " in your main configuration settings)
