Do you have something like this in your olsrd.conf (especially the version 
number of the plugin is important, the README is out of date...) ?

LoadPlugin "olsrd_secure.so.0.5"
{
    PlParam     "Keyfile"   "./olsrd_secure_key.conf"
}

In addition to this you need a keyfile exactly 128 Bit (16 bytes) long 
distributed on all nodes.

These two things were enough (for my setup) to get the "secure" plugin 
running. (I write "secure" because all the authentification of this plugin is 
done by a symmetric key, so it does not provide much more security that a 
good WPA2 encryption on your net unless you share the WLAN with other persons 
who must not send olsr routing messages).
