[Freeipa-users] FreeNAS Authenticating Againts FreeIPA

[Youenn PIOLET]

Hi Chris,

First, to be sure were on the same page:
Without IPA, to make CIFS users authenticate against directory in a classic
LDAP implementation, you need to extend your LDAP tree with Samba schema.
The FreeNAS documentation is a bit light on this subjet and previous
FreeNAS versions (stable 9.3 included) used to mess up rfc2307bis/rfc2307.
I think it is fixed now, and know nothing about your 9.2 version. Wrote
some messy stuff about it here:
https://github.com/uZer/rootools/blob/master/ldap/integrations/ldap.integration.freenas.md

To make CIFS users authenticate or FreeIPA recent versions (I only tried
with 4.1), I suggest you to start by reading some of our investigations in
this thread:

[Freeipa-users] Ubuntu Samba Server Auth against IPA
https://www.redhat.com/archives/freeipa-users/2015-August/thread.html#00000

When we discuss about this in august, I've spend almost a week trying to
make this integration with FreeNAS/FreeIPA work. I quit FreeNAS without
fully understand why it didn't work, and moved our CIFS to a dedicated
Centos server. Matt arrived with a similar situation in Ubuntu.

To quickly summarize the issue, FreeNAS and Ubuntu CIFS work by default
with ldapsam.so module. FreeIPA developpers have built a AD trust exchange
possibility with a custom ipasam module that isn't compiled yet for Ubuntu
or FreeNAS. This module gives the possibility to use IPA AD trust
components (e.g. special schema in IPA's directory managing user/group
NT SID)

If you can't compile the module for FreeNAS / FreeBSD, you may need to
extend 365directory with Samba schema.
You will need to find a way to generate the new attributes when adding
users or groups in FreeIPA, and a way to store password in a CIFS/NT
understandable way. I don't suggest you to follow this dark path.

You can also quit FreeNAS and migrate to CentOS with ipasam as I did ;)

Good luck in your experimentations, I hope you will succeed!
