Mr. DeKok,

On this new install of freeradius I used the ldap config suggested by this

Note that on this page, as in my prior config, the listed entry for filter
is  *filter = "(uid=%{%{Stripped-User-Name}:**-%{User-Name}})"*

I erased that an made a copy of mods-available/ldap and no longer have the
issue with the incorrect filter in radiusd -X output.

There seem to be some problems with this page, and some general gaps in
documentation for enabling modules.. for example this search returns no
