Referral following is not yet included in teh LDAP API (cf https://issues.apache.org/jira/browse/DIRAPI-61?jql=text%20~%20referral%20ORDER%20BY%20key%20ASC) So the only solution for you, atm, is to implement it on your side :/ > > Second, with regard to following referrals, assuming the above works to > just make the client follow referrals, is there any way to limit the number > of hops the client takes in following referrals?

I do not see anything similar in the Apache API for limiting - > am I missing it? No, you aren't missing anything. Cf https://issues.apache.org/jira/browse/DIRAPI-179?jql=text%20~%20referral%20ORDER%20BY%20key%20ASC > > Finally, assuming there isn't anything built-in to the API to limit > referral hops, I see that there is a getReferralLength() method in the > ReferralImpl class, but it's unclear what is meant by "referral length?" > Is this referring to the number of hops, or some other "length" associated > with referrals? Oh, it's a purely interal method that is used by the message encoder. It contains the length of the BER encoded URL. -- Emmanuel Lecharny Symas.com directory.apache.org
