Re: slapd-relay and slapo-rwm questions

So, I've been playing with slapo-relay and slapd-rwm to try and make it so that I can meet the expectations of different email clients that query my directory. This has led to a few questions:

(1) If your root is "dc=example,dc=com", and the entries you are interested in rewriting are in "cn=people,dc=example,dc=com" and the suffix you want to use virtually is "cn=outlook,dc=example,dc=com", how do you configure this? My attempts at doing this gave me the following error:

<suffix> namingContext "cn=outlook,dc=example,dc=com" already served by a preceding hdb database serving namingContext "dc=example,dc=com"

The same rules for slapd.conf ordering still apply - the most specific DN's must appear before the less specific DN. So you must define

database relay
suffix cn=outlook,dc=example,dc=com

database hdb
suffix dc=example,dc=com

(2) How do you get it to map the entry DN results to the new base? With "cn=people,dc=stanford,dc=edu" being mapped to "cn=outlook,dc=example,dc=com", the entries DNs returned all show "cn=people,dc=stanford,dc=edu" instead of "cn=outlook,dc=example,dc=com":

ldapsearch -LLL -x -h ldap-dev1 -b "cn=outlook,dc=example,dc=com" "cn=quanah*"
dn: suRegID=85e49978f61311d2ae662436000baa77,cn=people,dc=stanford,dc=edu

You still need to configure the suffixmassage.

(3) How do you map attributes to attribute names that don't exist in your schema? Since this is really about what gets displayed back to the client, I don't see why there is a requirement that the mapped-to attribute name must exist in your schema.

Everything that the local slapd returns directly to a client must exist in the local slapd's schema. You can only get away with using undefined schema elements when forwarding queries to a remote server, and even then you shouldn't - you should import the remote schema into the local slapd.

Remember, we don't support "schemachecking off" any more - we expect everything that we touch to have valid schema definitions.
