I have found a lot of documentation for FreeRADIUS v2, dating from 2011 and 2014, etc. But no clear step-by-step to enable LDAP for v3. My server is version 3.0.15. I have worked through the initial setup on the http://wiki.freeradius.org/guide/Getting-Started <http://wiki.freeradius.org/guide/Getting-Started> and was able to connect with “Access-Accept”. But now I want to connect an LDAP server (specifically, a VLDAP server from OneLogin). I have all their docs, and have all the base DN and Bind DN info. But the documentation at http://wiki.freeradius.org/modules/Rlm_ldap <http://wiki.freeradius.org/modules/Rlm_ldap> seem to “start in the middle” for me. It says you "can"…

Edit raddb/mods-available/ldap. Configure it.
i.e. *read* the comments. They tell you what the options do, and how they work. Fill in the configuration as necessary.
Start the server in debug mode. Send it a test packet using "radtest". Use a name/password that's in LDAP.
If it gets Access-Accept, you're good!
If not, *read* the debug output to see what it's doing. If you don't understand it, post it here.
It really is that simple. The "radtest" example *should* work if the LDAP module (a) talks to the LDAP server, and (b) is configured to search the right part of the LDAP tree.
The default configuration is designed to work with minimal edits. So do minimal edits, and it will work.
