freeradius + ldap (AD) + dot1x

[Paweł Grzęda]

Hello,

I'm newbie at FreeRADIUS. I'm trying to prepare a solution which will
provide authentication for PC/laptop's in corporate network. I need this
for Cisco switches and Ubiquiti APs/controller. There is Samba4
configured as domain controller which is central authentication point. I
installed Freeradius 3.0.14 on Fedora 25. I red all the man pages and
documentation stored in configuration files and to be honest it's huge
amount of information which is not clear for a newbie. I also used
tutorial which seems to be third-party, however link was on official
freeradius wiki I think.

Tutorial:

http://confluence.diamond.ac.uk/display/PAAUTH/Using+LDAP+as+authentication+source

I use start_tls to securely bind to LDAP (which is Samba4 AD DC) and the
binding works, however I still can't get Access-Accept message. I think
my problem is related to clear-text passwords (warning about no known
good password), however I don't know how to fix it. Is it a way to
configure this to be securely?
