Hello,

My PacketFence ZEN install seems to be having some trouble, or at least I
am. The background is that this is a fresh deployment for lab purposes.
Installation was completed following the installation guide. Now, I'm
trying to setup a basic wireless configuration to use a local source for
user authentication (not AD) to work with a Meraki AP. I have a little
experience configuring FreeRADIUS to work as the backend for Meraki in such
a setup, but have not run into this particular issue before.

At this point, in the RADIUS audit logs there's a REJECT with this reason:
mschap: Program returned code (1) and output 'Reading winbind reply failed!
(0xc0000001)'

Cursory research suggests this is a permissions issue. Checking permissions
suggests that the pf user is a member of wbpriv and also that wbpriv has
read permissions on /var/lib/samba/winbindd_privileged/.

[root@PacketFence-ZEN ~]# lid pf
 apache(gid=48)
 wbpriv(gid=88)
 pf(gid=989)
 fingerbank(gid=988)

Because this is a lab, I went ahead and attempted to add permissions to the
folder to see if that resolved the error:

[root@PacketFence-ZEN ~]# chmod +r /var/lib/samba/winbindd_privileged/
[root@PacketFence-ZEN ~]# chmod +w /var/lib/samba/winbindd_privileged/
[root@PacketFence-ZEN ~]# chmod +x /var/lib/samba/winbindd_privileged/
[root@PacketFence-ZEN ~]# ls -l /var/lib/samba/
total 0
drwxrwxr-x. 2 root printadmin 6 Oct 30 22:32 drivers
drwxr-xr-x. 2 root root       6 Oct 30 22:32 lock
drwx------. 2 root root       6 Oct 30 22:32 private
drwxr-xr-x. 2 root wbpriv     6 Oct 30 22:32 winbindd_privileged

Curiously, it did not change the write permissions on the folder, but did
add read and execute for "other" users. The issue persists with the same
log entry, even after rebooting the server.

I'm quite stumped. I have configured an htpasswd file to act as the
back-end authentication source. I setup a profile to match on
Wireless-8021x-EAP. I configured matching RADIUS shared secrets on the
device and PF.

Anyway, any pointers or suggestions are much appreciated. Thank you and
have a great day, everyone!
