Today I tried Dave Koelmeyer’s helpful guide to setting up LDAP authentication from an Ubuntu guest VM to OpenDJ.
To put it mildly, I am still learning about VirtualBox networking. Found out that inside an Ubuntu 10.10 desktop guest I installed to learn about OpenAM, the IP for the host is 10.0.2.2. YMMV.
I did a WebStart install of OpenDJ from last night’s build. To check that I could get to OpenDJ on the host from the guest, I got the ldap-utils package (sudo apt-get install ldap-utils), and searched for a test entry I had created (uid=mark) from inside the guest.
$ ldapsearch -x -h 10.0.2.2 -p 1389 -b dc=example,dc=com uid=mark # extended LDIF # # LDAPv3 # base with scope subtree # filter: uid=mark # requesting: ALL # # mark, People, example.com dn: uid=mark,ou=People,dc=example,dc=com objectclass: person ... yada yada yada ...
Thanks to Dave’s clear explanation, upon restart It Just Worked™ 
After that, I added Joe Bloggs and Babs Jensen under ou=People,dc=example,dc=com by using the OpenDJ Control Panel. Hence the screenshot at the top of this entry.
