Hi everybody,
I ask for your help because I'm going craizy with this.
I've an Acces Point configured to ask my radius server for
authentication, this servers uses as a backend an openldap server with
SSHA passwords on it. I've followed all the manuals and documentation
I've found and I can't get this to work.
The problem as far as I can see is related to the outer tunnel, it seems
that the user "anonymous" cannot be authenticated and everthing ends
there. Of course, I've not created that user anywere as I understand
that this is not needed to be done as this is a "dummy" user until the
inner tunnel is stablished. Here is the output of freeradius -X with a
request from a windows XP secureW2 client, hope you can help me:
