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

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'.).

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))"

# requesting: ALL

# 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:
[...]

Update in progress, 22 seconds elapsed
[ldap://idc02.my.dom.ain:389] reports: Update failed! Status: [Error

And on idc02 (the working server), in
/var/log/dirsrv/slapd-MY-DOM-AIN/errors I find lines stating:

It seems that idc02 remembers something about the old replica.
Any hint?
Thank you in advance,

IPA CA allow CSR SAN names in external domains
by Steve Dainard
Hello
I have a RHEL7 IPA server installed as a subordinate CA. I'd like to be
able to add SAN's for a different dns domain than exists in the IPA realm.
The dns for 'otherdomain.com' is handled by active directory which my IPA
server has a cross-forest trust with.
ie:
host: client1.ipadomain.com
certificate: CN = client1.ipadomain.com, SAN = client1.ipadomain.com,
servicename.otherdomain.com
When I try to submit this CSR with 'ipa-getcert request' the IPA server
denies with: "The service principal for subject alt name
servicename.otherdomain.com in certificate request does not exist"
It seems that the default CAACL enforces a profile named
'caIPAserviceCert', but I'm having some trouble determining what can be
modified (or cloned and changed in a new profile) that would allow the CA
to sign a CSR that contains *.ipadomain.com and *.otherdomain.com in the
SAN.
This is the only section in the profile that contains SAN:
policyset.serverCertSet.12.constraint.class_id=noConstraintImpl
policyset.serverCertSet.12.constraint.name=No Constraint
policyset.serverCertSet.12.default.class_id=commonNameToSANDefaultImpl
policyset.serverCertSet.12.default.name=Copy Common Name to Subject
Alternative Name
Thanks,
Steve

freeipa with sudo and 2FA (OTP)
by John Ratliff
I'm trying to setup freeipa with OTP. I created a TOTP under my user in
freeipa and updated my user to use 2FA (password + OTP).
When I try to do sudo, it only asks for my password and it fails every
time (presumably because it isn't getting the OTP first).
I didn't see anything useful in the sss_sudo logs, even after adding
debug_level = 6 in the config.
What can I do to further troubleshoot this?
Thanks.

Is that Java regression again that happened a month or two ago?
Thank you all.

Problems after replacing SSL certificates
by Andreas Bulling
Dear all,
I have recently started using FreeIPA (4.8.1 on Ubuntu) and now wanted to replace the original SSL certificates for the web UI and the LDAP server with official ones issued by our university.
I've followed the procedure described here (no errors):
https://www.freeipa.org/page/Using_3rd_part_certificates_for_HTTP/LDAP
I could confirm in the browser that the certificate for the web UI has been replaced and I therefore assume so has the LDAP certificate. Authentication from other hosts/services using LDAP still works but in the server log file I see errors like these for all hosts in the domain:
Apr 20 19:57:11 auth krb5kdc[24895]: AS_REQ (8 etypes {18 17 20 19 16 23 25 26}) X: NEEDED_PREAUTH: host/X@X for krbtgt/X@X, Additional pre-authentication required

Apr 20 19:57:11 auth krb5kdc[24895]: closing down fd 12
Also, ipa-certupdate on the respective clients shows
ipa-certupdate
trying https://X/ipa/json
[try 1]: Forwarding 'schema' to json server 'https://X/ipa/json'
cannot connect to 'https://X/ipa/json': [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:727)
The ipa-certupdate command failed.
Also, I can't login to the web UI anymore. I tried
ipa-getkeytab -s X -p HTTP/X@X -k /var/lib/ipa/gssproxy/http.keytab
on the freeipa server (followed by ipactl restart) but this didn't help.
Any idea/suggestions for how to get everything working again?
Thanks a lot!

User in AD not found by IPA
by Marc Boorshtein
We added a new account to AD that has a domain trust with FreeIPA. This
one user is having an issue where IPA can't find him. The user is in the
same OU as other users that work fine. The user is unlocked
(userAccountControl is 512) and the userprincipalname is set. When I try
to add the user to an id view or an external group IPA gives me the error
"trusted domain object not found" . Not really sure where to look next to
figure out what's wrong. We see the user when we make LDAP calls to AD.
Thanks

freeIPA Status Debian/Ubuntu
by Nico Maas
Hello there,
with the decline of CentOS I need to migrate away from CentOS 8 to something different.
I just wanted to ask how currently the status of the Debian or Ubuntu versions of freeIPA is - and if there is any possibility to migrate freeIPA installation / "backup and restore"?
Best regards,
