To import Challenge Response Passwords into eDirectory is somewhat challenging and not at all well documented.
Below is using a previous Cool Solution or example code in a more useful way. It takes a bit of setup to get working, but once it's going the process of importing the Challenge Response passwords in is a trivial one.
First. You need to trust the SSL Certificate of your LDAP Server since the NMAS Method uses LDAP from within the IDM Driver. First export out the public key (not private key) of the "SSL Certificate IP" or whichever certificate is assigned to the LDAP Server using iManager to a Base64 file format. Then on the IDM server use KeyTool to import it.
cd /opt/novell/eDirectory/lib(maybe 64 if you are running 64bit)/nds-modules/jre bin/keytool -importcert -trustcacerts -alias idmcert -keystore lib/security/cacerts -storepass changeit -file LDAPCERT.B64
Only change LDAPCERT.B64 to whatever is the Base64 name of the file your exported.
Then you can import in the attached Challenge Response Import.xml into Designer. There is also a bug in designer that prevents loading up XML in a ECMAScript, so you also need to open the ChallengeResponseES.TXT into your favorite text editor, then paste that over the top of the ChallengeResponse ECMAScript included in the driver.
The last step is to put the NMASToolkit.jar into the /opt/novell/eDirectory/lib/dirxml/classes directory so that IDM knows where to load it. Change this depending on the platform you are working on.
After you have imported the SSL Certificate into your keystore and put in NMASToolkit.jar, you will need to restart eDirectory to get the changed picked up.
Then you can have a CSV file with the following Files:
CN,FullName,Count (number of questions and answers),Question1,Answer1,Question2,Answer2.........
And it will import them into the driver, and call the ECMAScript, and over write any existing challenge & response questions and answers the user had set.
