  Which should be clear.  The server is unable to get the Cleartext-Password from LDAP.  As such, it can't do MS-CHAP.

 There *is* documentation saying what we need.  And it says DO run "radius -X".  And DON'T run anything else.

  The documentation also says DON'T post config files.

  If you want to fix computer things, it helps to read the documentation.

  If you *read* the debug output, the message about Cleartext-Password is from the "inner-tunnel" virtual server.  So ... go fix that.

  Read what you've done to the "inner-tunnel" virtual server, and ask yourself: "Where is Cleartext-Password supposed to be coming from?"

  There's a reason the documentation says "make small changes to the config files and test them".  In this case, you've done huge edits to "inner-tunnel", and broken it.

  And the above comments about reading the docs are *not* just me being an asshole.  The *entire set of config files* you posted to the list was unrelated to the problem.  So posting them is useless.  Which is why we don't ask for them.  And the bizarre fascination by many people with running "radiusd -Xxxxxxx" is just confusing to me.
