FreeIPA new network with DNS
by Jason Dunham 17 Oct '19

17 Oct '19

I am trying to set up a small office of software developers with FreeIPA. My ipa-server-install fails with "DNS zone example.com. already exists in DNS and is handled by servers foo1.myisp.net...". We do have basic hosted dns for our few public facing servers but I want to run an internal DNS on the LAN (and on the OpenVPN) to do name resolution. We don't currently have any AD or Kerberos, this is basically a new company with just a few people and a few workstations and will probably never grow very large without massive infrastructure changes that would be way out of scope for what I am trying to do. I was going to set up the internal computers as workstation1.internal.mycompany.com, workstation2.internal.mycompany.com, etc. since my understanding is that I can't do it without a subdomain since the primary domain DNS server already exists. I am putting this on a new server with a fresh install of CentOS 8. The ipa server is ipa.mycompany.com, or is it supposed to be ipa.internal.mycompany.com? I was trying to use all the defaults when calling ipa-server-install --setup-dns, but I don't really understand where to tell it about the subdomain. None of the many tutorials I have read seem to deal with my use case even though it seems like something lots of people would want to do. Am I using the right tool for this job? Am I just not finding the right web page that makes it easy? Can I run a small network with about 10 hosts and about 10 users on one freeipa host? I also have a separate box for pfsense/openvpn and maybe I could run a failover dns server on that, but I can't even get the main server running. Thanks in advance for any help with this.

Commands ipa topologysegment-find/show are confusing
by Jesús Marín García 16 Oct '19

16 Oct '19

Hello everyone: These days I have been doing a freeipa upgrade on a production cluster, what requires to perform multiple operations on the cluster for doing it without service interruption. One of the tasks was to ensure the topology is a complete graph, where each node have a connection with all the other nodes. In order to get the current topology, the command is `ipa topologysegment-find ca/domain` But this is confusing since there is another command named `ipa topologysegment-show...`. A user could expect the following behaviour: - topologysegment-show -> List all the elements, since "show" means you want to see something in general terms. - topologysegment-find -> List filtered elements by a given value, since "find" means you want to see something concrete. This is the same with other topics of the IPA command. I think this sould be changed in order to be more clear. My proposal is as follows: - "topic"-list -> in order to list all the elements. - "topic"-find -> in order to get certain elements filtered by a given value. - "topic"-detail or "topic"-describe -> in order to see the details of a given element. What do you think? Do you also find current commands confusing? Thanks, Regards

There are problems when using forest trust to Active Directory. AD simply doesn't support single label domains anymore. The real problem is that you might not know whether you would need to integrate with AD at the time IPA is deployed. Realm cannot be changed afterwards, so if you'd stuck with single label domain, you stuck forever. With no reasonable migration path to export all data including hashed keys for Kerberos principals to a different deployment (with different realm), you would block yourself forever. -- / Alexander Bokovoy Sr. Principal Software Engineer Security / Identity Management Engineering Red Hat Limited, Finland

Single label domain usage
by Sven Ludwig 16 Oct '19

16 Oct '19

Hi @audience, I'd like to ask is there is a chance to continue using single label domains with freeipa. We learned the hard way that this feature was restricted to use. It cannot be bypassed by any command line option. I found that this all comes down to a check in the ipalib/util.py, which now counts the number of tokens in a list split by dots. It's easy to patch, but I am asking myself for the reason to disallow this without being able to overwrite this in command-line? Are there any further problems with using single label domains currently or in the future? Regards, Sven

Re: How to make ipa root certificate available system wide
by Kevin Vasko 16 Oct '19

16 Oct '19

So I went back and read, reread, studied what you wrote and I think I’m following you. I’m really unfamiliar with certs and the tools around it so forgive the ignorance. So what I ended up doing is spinning up a CentOS7 VM and installing everything on it, adding it to the FreeIPA realm etc. and followed your instructions/email. I ran the modutil -dbdir sql:./mozilla/firefox/9zd63dro.default/ -list It returns the list of the PKCS #11 Modules like I listed in my previous email. However, it only showed a single item “NSS Internal PKCS #11 Module”. To look at what keys it had I ran certutil -d sql:./mozilla/firefox/9zd63dro.default/ -h “NSS Internal PKCS #11” -L This seemed like it returned all of the system wide certs. Including my self signed internal lan cert from freeipa. Should it have? That’s where I’m getting confused with your comment in your email when you mentioned the p11-kit-proxy and where it’s coming from, how it was added (if needed) as you said it was providing all of the system wide certs? At this point this is where things took a detour and I think it’s part of my confusion, which I think is unrelated, but I was using Firefox, all of the certs are there in the system based on the commands you showed. However, every time i would visit my http server Firefox would throw a SEC_ERROR_REVOKED_CERTIFICATE I pulled my hair out for 2 hours, deleting the .mozilla folder, recreating it, looking at certs, trying to manually copy certs into the cert db etc. Until I got fed up and tried Chrome...i downloaded chrome installed it ran it, checked the certs db looked at the certs and verified my internal cert was listed just like firefox. I visited the http server in chrome and it worked perfectly. No changes, which I believe is what you would expect. I then went and tried the same thing on Ubuntu. I know you mentioned that I have to add the certs manually as Ubuntu doesn’t have the same functionality. So I just manually added my ipa.crt to firefox and then got a SEC_ERROR_REVOKED_CERTIFICATE installed chrome on ubuntu machine and manually imported the ipa.crt into chrome, went to the http and chrome worked fine. So now I have no idea where I’m getting this SEC_ERROR_REVOKED_CERTIFICATE So now on a freeipa realm joined host. It seems that CentOS7 - Firefox gets a - SEC_ERROR_REVOKED_CERTIFICATE Chrome - Works out of the box Ubuntu 18.04 - Firefox gets after manually adding cert- SEC_ERROR_REVOKED_CERTIFICATE Chrome - works after manually adding the ipa.ca cert through GUI. Is there some obvious reason why firefox would throw that error message but Chrome wouldn’t? This stuff is making my head spin. > On Thu, Oct 10, 2019 at 2:45 PM Kevin Vasko <kvasko(a)gmail.com> wrote: > > So you are saying that if the p11-kit-trust module is available it > should be automatically adding the system wide trust store into the > internal Firefox cert store? > > This is the out of my commands.

Hey y'all, What are the pros and cons of using and external or internal CA for FreeIPA/IdM? I am trying to decide which to do but having trouble finding a lot of info about why I would want to do one or the other.

MFA authentication for some service only?
by William Kwan 15 Oct '19

15 Oct '19

Hi, I ran some tests and was able to enable multi-factor authentication. What I have is a Fortinet firewall hooks up to LDAP on FreeIPA for VPN login. By turning on MFA for an user, when the user SSH to a Linux host, the MFA is required also. Is there anyway to have MFA on VPN but not on other services such as SSH? ThanksW

Re: Ipa user can't login via ssh

Please keep freeipa-users in the responses. Elhamsadat Azarian wrote: > Hi Rob > I did it and i got this answer: > > Access granted : false > > What can i do now? IPA ships with a default HBAC rule, allow_all, which allows all users to authenticate on all hosts. I can only assume you've deleted or disabled that, and that's fine. But if you do then you need to create the set of rules to grant access to hosts for the appropriate users. To provide specific assistance you'd need to share a bit of internal details, current HBAC rules, etc. It is understandable if you can't do that. But basically you need to evaluate your HBAC rules to find out why this user can't log into hosts. The user may be missing from a group, for example. rob > > On Mon, 14 Oct 2019, 18:07 Rob Crittenden, <rcritten(a)redhat.com > <mailto:rcritten@redhat.com>> wrote: > > Elhamsadat Azarian wrote: > > I tryed to add HBAC rules to my user but it said : some operation > > failed.

/var/lib/sss/pubconf/known_hosts empty
by Vinícius Ferrão 14 Oct '19

Hello, The /var/lib/sss/pubconf/known_hosts file is empty on a new installed FreeIPA server. I’ve already joined a machine to the domain but the file is still empty. I can’t get it populated, already rebooted and/or restarted sssd without success. Looking on the web I came across this bug: https://bugzilla.redhat.com/show_bug.cgi?id=1574778 It is Fedora related, but it’s the same version that I’m running, since I’m on CentOS 7.6. How can I check if is in fact this bug? Here are some errors on sssd_ssh with debug_level = 9 enabled: ==> /var/log/sssd/sssd_ssh.log <== (Tue Oct 8 21:10:37 2019) [sssd[ssh]] [sbus_remove_timeout] (0x2000): 0x55b758c55dc0 (Tue Oct 8 21:10:37 2019) [sssd[ssh]] [sbus_dispatch] (0x4000): dbus conn: 0x55b758c56e10 (Tue Oct 8 21:10:37 2019) [sssd[ssh]] [sbus_dispatch] (0x4000): Dispatching.
