Hi,
I am doing following steps in order to authenticate the user in my C program using OpenLdap API:
Program 1: 1. ldap init 2. ldap set option to version3 3. search the user using ldap_search_st to get the user DN 4. ldap simple bind with user-DN and password
Now I want to use referral chasing feature. For above program ldap search at step 3 returns NULL if user is not available
Therefore, I added rebindproc function to search the user-DN on other server The program is changed to:
Program 2: 1. ldap init server1 2. ldap set option to version3 3. ldap set option to rebindproc function 4. search the user using ldap_search_st to get the user DN 5. ldap simple bind with user-DN and password
In rebindproc, I am binding with root credentials and parsing referral URL to get the base DN. Here, I got the user-DN from refered server (server 2) in step 4. However, ldap simple bind at step 5 fails saying invalid credentials. It is correct, since the user is not present on server1.
Is there anything more I need to do, so that ldap_simple bind will happen with referral server (server2). What API shall I use to bind the user-DN to referral server?
