Re: FreeRadius and FreeIpa integration not working in our Lab setup

      FreeRADIUS: Using mschapv2 with freeipa for wireless authentication.
I am following the below links to use mschapv2 authentication to have
authenticate wireless users using FreeIPA+ Freeradius.
https://fy.blackhats.net.au/blog/html/2015/07/06/FreeIPA:_Giving_permissions...
<goog_2039148863>
https://fy.blackhats.net.au/blog/html/2016/01/13/FreeRADIUS:_Using_mschapv2_...
However, I am getting some bind errors when running radius in Debug
mode.The Debug report shows that ldap bind is unsuccessful due to invalid
credentials and am sure that bind credentials mentioned in *mods-available/ldap
*module is correct.Below is the same Debug report and module configuration.

However, when a user is trying to authenticate to wireless services,
getting a debug report as below and connection to wireless is failing:

However,just to troubleshoot, added a user profile in user config file at
sudo vim /etc/raddb/users and below is the same. And when trying to
authenticate with this test profile am able to authenticate and connect
to
network (QICAP_5G-2).

So, not really sure why authentication is failing for other user profiles
which are not added in the user config file and that is not the expected
behaviour.
Thanks

read the logs. I shortened the logs to make clear the important parts.
The truth is on the logs.
or, to make it even more clear:
ldap: WARNING: No "known good" password added. Ensure the admin user
has permission to read the password attribute
No password, no authentication.
