Hello,
I ran into a strange effect today (FR 3.0.12 on Debian Jessie).
We use LDAP extensively, nevertheless I forgot to enable the module.
I.e. I did not create the symlink in mods-enabled because I believed
it to be part of the Debian package freeradius-ldap.
Everything else was in place, like my ldap config in mods-available/ldap
and an Auth-Type LDAP {} statement in both sites-available/default
and sites-available/inner-tunnel.
The effect then is that on server start (or even just config check)
all modules get loaded, but the first module instantiation ends in
a crash. As it turns out, the first module to be instantiated
is rlm_ldap.
While my configuration was definitely quite inconsistent,
a crash might not be what you want either.
So here is my debug output:
