Question about /etc/pki/java/cacerts and password change
by Markovich 29 Nov '17

29 Nov '17

Hello FreeIpa community! I'm a bit confused about JKS "/etc/pki/java/cacerts". Am I right, that default password for this JKS is "changeit"? Can I change this password? If yes, shoud it be the same on all hosts connected to FreeIpa? Will it be problem later for FreeIpa? Should I somehow tell FreeIpa this password? Also what is the best practice to tell java to trust FreeIpa CA? Regards, Andrey

Deployment considerations - domain name
by Aljaž Srebrnič 29 Nov '17

29 Nov '17

Hello list, I’m managing the network for my hackerspace, and we’re moving to FreeIPA (from plain LDAP) to manage internal and external services. We have some services that are hosted on public, external machines (wiki, etc.) that members would authenticate to via Ipsilon OAuth2 that are under the main domain (e.g. wiki.example.org), and some internally hosted services that are under a subdomain (e.g. netbox.hq.example.org). My plan is to have a IPA replica on the ”outside” with Ipsilon for external auth, and a couple of local replicas (one of which is the ca master). The outside replica would be connected via VPN to the internal network, to avoid opening lots of ports to the outside world. I’m having some difficulties choosing the proper Kerberos domain, and in general putting together the ”external” world (example.org domain) and the ”internal” one (hq.example.com domain) because the DNS server on the main domain is under CloudFlare. Would getting a new domain just for FreeIPA be advisable?

Directory service stop and won't stay up when restarted
by Alexandre Pitre 29 Nov '17

29 Nov '17

Hi, I had two freeipa replica servers up and running in our german DC for nearly 2 months and this morning out of the blue they stopped working. Looking at ipactl status, both servers are reporting that their directory service is stopped. Trying to restart ipa only works from 2 minutes to an hour. Looking at the /var/log/dirsrv/slapd-DOMAIN-COM/errors there's no errors that show up before it crash. However, looking at /var/log/messages, this lovely segfault show up: XXXXXX kernel: ns-slapd[17507]: segfault at 8 ip 00007fb99e56149f sp 00007fb96bee83c0 error 4 in libslapd.s o.0.1.0[7fb99e483000+128000] Out of despair to get production back up and running quickly, I reinstalled one replica...it worked for an hour and came back with the same issue. We have 6 other freeipa replica running accross 3 different site with zero issues. We're running CentOS 7.4 with the latest packages, ipa-server-4.5.0-21 & 389-ds-base-1.3.6.1-21. Any clues why ? Thanks -- Alexandre Pitre alexandre.pitre(a)gmail.com

adduser using keytab does not work, using kinit credential it does
by Matt . 28 Nov '17

28 Nov '17

I try to add a user using a principal where has been received a keytab for, the user and it's group are owner, chmod is 600 as it should be. The user can create a valid credential using this keytab. When I call the user_add command I get the following error. Array ( [error] => Array ( [code] => 2100 [data] => Array ( [info] => Could not read UPG Definition originfilter. Check your permissions. ) [message] => Insufficient access: Could not read UPG Definition originfilter. Check your permissions. [name] => ACIError ) [id] => [principal] => testuser/ipa-01.mydomain.tld(a)MY.DOMAIN [result] => [version] => 4.4.4 ) Everything goes well when I do a 'kinit testuser' and created a credential and then call the user_add function again. Where could this go wrong ?

Get userstatus back from ldap login
by Matt . 28 Nov '17

28 Nov '17

Hi guys, I thought by default (because of security reasons) it was not possible to get back from a login if the useraccount exists when you login but it was possible to make some setting to have this available. Is someone able to tell me how to do this so my ldap clients het back the right status ? Thanks, Matt

Re: Expired passwords and generating an OTP token
by Aaron Hicks 28 Nov '17

28 Nov '17

Hello the list, It's here: https://pagure.io/SSSD/sssd/blob/master/f/src/providers/ipa/ipa_auth.c#_395 SSSD is not doing its job properly when a user has an expired password and an OTP token, and they should reset their password at the ssh prompt. When a user has an expired password it should ignore the OTP token during password reset process, and then disconnect. The condition where an expired or compromised temporary password is obtained by an unauthorised entity means that as long as the unauthorised entity does not have the OTP token secret, the worst they can do is reset your password. This condition is escaped when someone, either the user, a helpdesk agent, or an admin, resets the password to something the unauthorised entity doesn't know. The case of the unauthorised entity having both the password and OTP token is already recognised as a compromised state, so the code doesn't need to protect us from that.

Which would at least allow our customer management system to disable or delete their OTP token so they can reset their passwords. In addition to this, users are not able to reset passwords at the ssh login on hosts where 2FA is not enabled either! So this seems to be narrowing down on the bits of pam and sssd uset to authenticate the password change process. An interesting note is, kinit does not require OTPCODE. Finally, no users do not have access to the FreeIPA web interface or a host without 2FA. The 2FA secured host is to be their lander node into our network.

Even the ones that do not require 2FA. Feedback so far form Sumit indicates this is incorrect behaviour. As an attempt to get around this, I've tried adding a permission to the helpdesk role that would allow them to manage OTP tokens. I'll submit another thread on that.

Can you send me the PAM related messages form /var/log/secure or the journal which cover the failed attempt? And additionally the SSSD logs with debug_level=9 from the same time. Most important would be sssd_pam.log, sssd_domain.name.log and krb5_child-log. bye, Sumit

restrict parallel ssh logins on different freeipa systems
by Michael Frank 28 Nov '17

28 Nov '17

Hi, we run freeipa based on red hat 7.3 It is possible to determine if a certain user (idm user who can become root via sudo) is logged in on multiple idm machines and restrict for the user that only *one* login on a single server at the same time is allowed ? Any hints how to do this - or - is there something „built-in“ ? br, michael

WebGui Cert back to selfsigned
by Matt . 28 Nov '17

28 Nov '17

Hi Guys, Is there a proven way to set the WebGui cert back to a self signed one ? I have installed an expired 3rd party certificate and want to move back to a selfsigned cert and later on to an letsEncrypt one. Setting back the time before the expiration of the certificate on the server would be a start and also disable all nameservers in /etc/resolv.conf so the time is not updated on an ipa start/restart. But what then ? Is there no "reset command/way available" ? Thanks! Matt
