That error is coming from libldap - that is it's expansion of the error 
code passed to ldap_err2string().

Try enabling libldap debug options by setting the ldap_debug option in 
src/mod-enabled/ldap - you should refer to OpenLDAP documentation to see 
the meaning for the values you can set there.

The output is not easy to read, but tells you what libldap is doing as 
opposed to what FreeRADIUS is doing.
