Problem running IPA client on IPv6 only connection
by William Muriithi
Hello,
I have an IPA clients that has both IPv4 and IPv6 addresses. One of the
IPA client is in the office and hence can reach the IPA server on both IPv4
and IPv6. However, the client outside the LAN can only reach the IPA server
over IPv6.
I was able to enroll the external client fine over IPv6 and from the logs,
all clean. However, when I attempted to ssh, its not able to retreave the
user from IPA. The client in the office works fine. I can also make for
example LDAP queries and they work over IPv6 fine. It looks like kerberos
is somehow however using IPv4. I reached this conclusion after taking a
tcpdump when attempting to ssh to the server and the kerberos traffic from
the client to IPA is on IPv4.
What would I need to do on the IPA client for it to prefer IPv6? I am
aware I could remove IPv4 address from DNS, but that would break any
communication from IPv4 only systems. Any assistance would be appreaciated.

ssh key issues
by Andrew Meyer
I recently cleaned up a few server in my home lab. Deleted servers that I no longer needed. However It seems I have a server with an IP address that used previously. FreeIPA is reporting that it is in /var/lib/sss/pubconf/known_hosts but I can't reverse engineer the hostname by doing sshkey -R 1.2.3.4. I have run into this issue previously but it has bee quite some time. When I go to delete the line from /var/lib/sss/pubconf/known_hosts it is gone. If someone could help me that would be great. I didn't see anything on my FreeIPA master that indicated I did anything there.

Could not login with AD user
by Ronald Wimmer
Today I was not able to log in with an AD user to an IPA client within a
test setup. IPA users worked fine.
DNS is managed externally. I figured out that the DNS-Record of that
particular IPA client has not been created correctly. After having
corrected the DNS entry and having dropped the SSSD cache on that client
I could login with my AD user.
Do you have an explanation for that or was it just a coincidence?
Cheers,
Ronald

keycloak - the other way around?
by lejeczek
Hi guys.
I've only stumbled upon whole Keycloak thing thus go easy on
me please. I wonder if Keycload can be a "provider" to
freeIPA in some way?
One such a scenario where I think Keycloak might be a golden
egg - if it worked that is - is as a "middle-man" for user
base between(or from to) AD and freeIPA when full & legit
trust is not possible. Does that make sense?
many thanks, L.

freeipa/certmonger for openvpn user certificates
by Patrick Spinler
Hi,
I'm setting up an openvpn server and I'd like to use our already existing FreeIPA CA to issue user keys/certs for openvpn's use. Since our OpenVPN box is a freeipa client, I thought it'd be nice to use certmonger to issue and keep up to date these certs.
Ergo, I've created a certificate profile:
pat@apex-freeipa ~$ ipa certprofile-show --all OpenVPNUserCert
dn: cn=OpenVPNUserCert,cn=certprofiles,cn=ca,dc=int,dc=apexmw,dc=com
Profile ID: OpenVPNUserCert
Profile description: OpenVPN User Certificates
Store issued certificates: FALSE
objectclass: ipacertprofile, top
And also a CA acl. For experimentation (and working vs our test freeipa) I've left this as wide open as I can:
[pat@apex-freeipa ~]$ ipa caacl-show --all OpenVPN_User_Certificate_ACL
dn: ipaUniqueID=6dde33a6-7849-11e9-aa05-525400b52c7b,cn=caacls,cn=ca,dc=int,dc=apexmw,dc=com
ACL name: OpenVPN_User_Certificate_ACL
Enabled: TRUE
CA category: all
Profile category: all
User category: all
Host category: all
Service category: all
ipauniqueid: 6dde33a6-7849-11e9-aa05-525400b52c7b
objectclass: ipaassociation, ipacaacl
Then, on my openvpn server, I ask for a cert for use for one of my users (myself, in this case):
root@apex-openvpn:~# ipa-getcert request -f /etc/openvpn/client/pat.crt -k /etc/openvpn/client/pat.key -r -N 'CN=pat,O=INT.APEXMW.COM' -K pat -g 4096 --profile OpenVPNUserCert
New signing request "20190603014016" added.
But, it fails due to an access err vs the 'userCertificate' attribute of my account:
root@apex-openvpn:~# ipa-getcert list
(...snippy snip excess...)
Request ID '20190603014016':
status: CA_REJECTED
ca-error: Server at https://apex-freeipa.int.apexmw.com/ipa/xml denied our request, giving up: 2100 (RPC failed at server. Insufficient access: Insufficient 'write' privilege to the 'userCertificate' attribute of entry 'uid=pat,cn=users,cn=accounts,dc=int,dc=apexmw,dc=com'.).
stuck: yes
key pair storage: type=FILE,location='/etc/openvpn/client/pat.key'

If I look at the dirsrv log, here's the accesses I see for this request (trimmed off the date/time to make the lines a _little_ shorter):

To begin with, I note that this session does a BIND with 'dn=""', right at the beginning, it's essentially an anonymous bind, yah?
That operation near the end, here:
op=17 SRCH base="cn=caacls,cn=ca,dc=int,dc=apexmw,dc=com" scope=1 filter="(&(objectClass=ipaassociation)(objectClass=ipacaacl))"
seems like it might be kinda key. and indeed, if I attempt to run this by hand as an anonymous bind, I get no results:
root@apex-freeipa slapd-INT-APEXMW-COM# ldapsearch -x -h localhost -b dc=int,dc=apexmw,dc=com -s sub "(|(objectClass=ipaassociation)(objectClass=ipacaacl))"

# filter: (|(objectClass=ipaassociation)(objectClass=ipacaacl))
# requesting: ALL
#
# search result

# numResponses: 1
It's only if I run this as an _authenticated_ bind, that I can find my ACL:
root@apex-freeipa slapd-INT-APEXMW-COM# ldapsearch -x -D "cn=Directory Manager" -W -h localhost -b dc=int,dc=apexmw,dc=com -s sub "(&(objectClass=ipaassociation)(objectClass=ipacaacl))" cn

Is this (using certmonger to auto-issue signed certs/keys for my openvpn users) going to be essentially impossible to do, here? Do I need to go a more traditional route of creating a seperate keystore/certdb, issuing a CSR, and feeding that to FreeIPA to sign?
Any advice appreciated, and thanks in advance,

Broken ipa replica
by Giulio Casella
Hi everyone,
I'm stuck with a broken replica. I had a setup with two ipa server in
replica (ipa-server-4.6.4 on CentOS 7.6), let's say "idc01" and "idc02".
Due to heavy load idc01 crashed many times, and was not working anymore.
So I tried to redo the replica again. At first I tried to
"ipa-replica-manage re-initialize", with no success.
Now I'm trying to redo from scratch the replica setup: on idc02 I
removed the segments (ipa topologysegment-del, for both ca and domain
suffix), on idc01 I removed everything (ipa-server-install --uninstall),
then I joined domain (ipa-client-install), and everything is working so far.
When doing "ipa-replica-install" on idc01 I get:
[...]

And on idc02 (the working server), in

Any hint?

DNS record with all IPA servers
by Boris Behrens
Hi,
I am currently trying to cleanup our IPA installation and saw that all our
clients only got a single server configured, which doesn't sound good.
(we've currently got two IPA servers).
Is there some sort of record that can be used?
root@host1:/etc/ipa# cat /etc/ipa/default.conf
#File modified by ipa-client-install
[global]
basedn = dc=domain,dc=ca
realm = DOMAIN.CA
domain = DOMAIN.CA
server = ipa1.domain.ca
xmlrpc_uri = https://ipa1.domain.ca/ipa/xml
enable_ra = True
Cheers

certs: SAN without othername / NT Principal name
by David Harvey
Hi FreeiPA users,
I'm having great fun with a web app that hates the othername/ NT Principal
name included with certificates generated with ipa-getcert.
I've tried several variations but can't omit this part of the subject
alternative name. Is there any way to do so?
Thanks in advance,

geo replication - ? - concept of
by lejeczek
Hi guys.
This must have been asked/covered somewhere I think, as it
must be trivial concept/question many must have wondered -
can IPA, in supported manner with built-in way or not, do
'geo-repliacation' in some sense?
What I wonder specifically is - call it a secondary, backup
or a mirror site(of whole domain) which would _only_
receive(possibly synchronously) and be read-only but!...
that direction, the flow of main/primary -> secondary/backup
could be flipped, reversed(in relatively non-time consuming way)
Anybody done or contemplated such or similar thing and care
to share some thoughts?
many thanks, L.

ipa-ca DNS record - ?
by lejeczek
Hi guys.
What is 'ipa-ca' for and what should it point to?
Also, should IPA change that record ever?
Reason I ask - from the docs as I understand - it should
point to all CA servers in the domain, but it not happening.
many thanks, L.
