Hello, I'm struggling with Freeradius since a few days and cannot get forward. This is the message I get when I execute Freeradius in debug mode: 'Rejected: Realm does not have at least one dot separator' Ignoring "ldap" (see raddb/mods-available/README.rst) And this is what I get when I restart the computer, but when I restart Freeradius I don't get it.

Could you please give me a clue? Thanks in advance.
