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

ipa-getkeytab: PrincipalName not found
by Harald Dunkel
Hi folks,
maybe I missed something, but shouldn't admin have sufficient
privileges to run
# ipa-client-install --hostname stretch1.vs.example.de --no-ssh --no-sshd --no-nisdomain --no-sudo --no-ntp --no-dns-sshfp
# reboot
:
:
# kinit admin
# ipa-getkeytab -s ipa1.example.de -p HTTP/stretch1.vs.example.de -k /etc/apache2/apache2.keytab
?
ipa-getkeytab failed with
Failed to parse result: PrincipalName not found.
I would have expected it to create the principal on the fly.
"admin" was created at freeipa install time on the first server,
AFAIR. It is member of the "admins" and "trust admins" groups.
I am concerned that I corrupted something. Every helpful comment
is highly appreciated.

nfsidmap/nss_getpwnam fails to resolve users with IPA/NFSv4+krb5
by Robert Sturrock
Hi All.
We have IPA setup in an AD trust to support our Linux fleet. I’m running into a problem trying to get Ubuntu (16.04) clients to resolve names/ids on an NFS-mounted filesystem from an NFS server using NFSv4/krb5. Files and directories show up as ‘nobody’ or an incorrect numerical ID when listed with ‘ls’. RHEL7 clients seem to working fine with a very similar configuration (as far as I can tell).
The particulars are:
- AD forest has domains ‘localdomain’ and ‘student.localdomain’ (my user identity is ‘user@localdomain’)
- IPA domain is ‘ipa.localdomain’
- The NFS server (RHEL7) and clients (Ubu16.04, RHEL7) are both enrolled to IPA (with 'Domain=ipa.localdomain’ in /etc/idmapd.conf).
I have mounted the NFS volume on the clients with a simple:
mount -t nfs4 nfs-server.ipa.localdomain:/export /mnt
Listing my directory as myself (‘rns@localdomain’) on the Ubuntu client, I see:
$ ls -ld rns
drwx------ 18 nobody 4294967294 4096 Oct 25 15:18 rns
.. with these corresponding nfsidmap messages:
Oct 25 16:49:42 ubuntu-16.04-client.sub.localdomain nfsidmap[6163]: key: 0x2c254c26 type: uid value: rns@localdomain(a)ipa.localdomain timeout 600
Oct 25 16:49:42 ubuntu-16.04-client.sub.localdomain nfsidmap[6163]: nfs4_name_to_uid: calling nsswitch->name_to_uid

Oct 25 16:49:42 ubuntu-16.04-client.sub.localdomain nfsidmap[6163]: nss_getpwnam: name 'rns@localdomain(a)ipa.localdomain' does not map into domain 'ipa.localdomain'
Oct 25 16:49:42 ubuntu-16.04-client.sub.localdomain nfsidmap[6163]: nfs4_name_to_uid: nsswitch->name_to_uid returned -22
Oct 25 16:49:42 ubuntu-16.04-client.sub.localdomain nfsidmap[6163]: nfs4_name_to_uid: final return value is -22
.. whereas on the RHEL7 client, I see:
$ ls -ld rns
drwx------. 18 rns@localdomain rns@localdomain 4096 Oct 25 15:18 rns
Oct 25 16:56:23 rhel-7-client.sub.localdomain nfsidmap[30590]: key: 0xf113fd2 type: uid value: rns@localdomain(a)ipa.localdomain timeout 600

Oct 25 16:56:23 rhel-7-client.sub.localdomain nfsidmap[30590]: nss_getpwnam: name 'rns@localdomain(a)ipa.localdomain' domain 'ipa.localdomain': resulting localname 'rns@localdomain'
Oct 25 16:56:23 rhel-7-client.sub.localdomain nfsidmap[30590]: nfs4_name_to_uid: nsswitch->name_to_uid returned 0
Oct 25 16:56:23 rhel-7-client.sub.localdomain nfsidmap[30590]: nfs4_name_to_uid: final return value is 0
Oct 25 16:56:23 rhel-7-client.sub.localdomain nfsidmap[30592]: key: 0x2125a5d2 type: gid value: rns@localdomain(a)ipa.localdomain timeout 600
Oct 25 16:56:23 rhel-7-client.sub.localdomain nfsidmap[30592]: nfs4_name_to_gid: calling nsswitch->name_to_gid
Oct 25 16:56:23 rhel-7-client.sub.localdomain nfsidmap[30592]: nfs4_name_to_gid: nsswitch->name_to_gid returned 0
Oct 25 16:56:23 rhel-7-client.sub.localdomain nfsidmap[30592]: nfs4_name_to_gid: final return value is 0
Why does the Ubuntu client's nfsidmap think that my identity doesn’t map into ‘ipa.localdomain’ and therefore (presumably) returns the error code ‘-22’?
(My identity resolves ok from the shell, using ‘id rns@localdomain’ and I can login and use local filesystems without issue).
The idmapd.conf looks like this:
[General]
Verbosity = 4
Pipefs-Directory = /run/rpc_pipefs
Domain = ipa.localdomain
Local-Realms = LOCALDOMAIN, STUDENT.LOCALDOMAIN, IPA.LOCALDOMAIN
[Mapping]
Nobody-User = nobody
Nobody-Group = nogroup
[Translation]
Method = nsswitch
Any pointers appreciated!
Regards,
Robert.

IPA server upgrade fails with KDC error
by Johannes Brandstetter
Hi,
I'm trying to upgrade FreeIPA through ipa-server-upgrade from 4.4 to 4.5. The command fails with an "ACIError: Insufficient access:" . I find in the kdc log that it complains about " Database module does not match KDC version - while initializing database for realm..."
Does anybody know how to fix this?

using freeipa with an AWS elastic load balancer
by ridha.zorgui＠infor.com
I set up a FreeIPA master and replica behind an elastic load balancer in AWS cloud. FreeIPA Clients will be contacting the replica and the master sever through the load balancer so the dns name used when configurting the clients is the ELB CNAME. The problem is when retreiving ldap data and during the authentication, the SSL handshake fails as the certificate sent back from the master or replica has a hostname different than the one used in the sssd ( the ELB CNAME). so the connection is terminated. There is a workaround which is the use reqcert=allow but this bring a security issue with a MITM attack. another solution i found is the use SAN. I was able to add the ELB DNS as a SAN in freeipa servers certificate. i made sure it is there by downloading the certificate and checking that the elb san exist but when testing it the same problem remain. Please help.

Web UI login fails after upgrading to 4.5
by Marius Bjørnstad
Hi all,
After I upgraded to FreeIPA 4.5 (on CentOS 7), I get an error "Login failed due to an unknown reason" on the web UI, no matter if I use the admin user or my personal user. From what I can tell, all the ipa commands work fine on the command line, and kinit also works fine.
I have included some output from /var/log/httpd/error_log below. It would be great if someone could make a guess (or better) at what is going wrong, or which logs to look at, etc.
When I run the command in the CalledProcessError, I get a password prompt for WELLKNOWN/ANONYMOUS(a)OUS.NSC.LOCAL (the second part is the realm name).
Thanks,
Marius

Unable to use externa groups or users, truster domain object not found
by Henrik Stigendal
Hello everyone,
I’m new to this and are trying to setup a working trust against an AD forrest, I seem to have a working trust but when I try to reference external groups (or users) I get:
# ipa group-add-member ad_users_external --external "AD2\Domain Users"
[member user]:
[member group]:
Group name: ad_users_external
Description: AD users external map
Failed members:
member user:
member group: AD2\Domain Users: trusted domain object not found
-------------------------
Number of members added 0
-------------------------
I enable some logging and last in the mail is the output there from the command above, any suggestions what could cause this? Current version of IPA is 4.5.
Regards
Henrik

upgrade to ubuntu 17.10 fails
by David Harvey
Hi wisdom of the list,
I know I am an edge case with running on ubuntu, but hoped someone might be
able to shed some light.
A bit of background. I'm trying to test upgrades without potentially
hosing my existing services, so I have cloned the VM, given it a new IP
address, updated hosts file and pointed DNS somewhere that doesn't know
about the real IPA services (8.8.8.8) so it won't try and sync or replicate.
Attempting to upgrade hits a snags or two, some described in bugs already
like the pki version number confusing the apt scripts
https://bugs.launchpad.net/ubuntu/+source/freeipa/+bug/1703051 ). The one I
can't work around however is below.
It seems deeply unhappy, and restarting the services result in the
dogtag-pki web page being available until a login attempt is made (as
occurs during the ipa-server-upgrade) after which point it bombs with a 500
error.
Could the below caused by
https://bugs.launchpad.net/ubuntu/+source/freeipa/+bug/1716842 ?
Any advice appreciated, as I think even when 18.04 hits with the proposed
updates to rely on to tomcat 8.5, I'll still need to upgrade via 17.10
which seems currently fraught! If it relates to my method of cloning the
VM, is there a better way of testing upgrades without potentially hosing
the existing live systems?
Thanks in advance,
David

freeipa sudoers help
by Andrew Meyer
In preparation for a migration I am trying to setup sudoers within freeipa. I have about a dozen people that will need to sudo to another user and run commands. However I want to add all the commands for that user into my rule.
would this be best practice to add ALL the commands into 1 rule? or should I do a sudocmdgroup?
ipa sudorule-add-allow-command --sudocmds "/usr/bin/vim" files-commandsWould I just put a comma after each command? Or should I do this all individually and add all the commands to a cmd group?

Accessing KRB5 NFS from local system accounts
by Gordon Messmer
I'm troubleshooting a problem: A local system account (daemon) needs to
access a file on an NFS4 filesystem with sec=krb5. My understanding is
that only processes which have a Kerberos ticket are able to access
files on such a filesystem, and that seems to be the case on the system
I'm troubleshooting.
Suppose I need a keytab to identify the "daemon" user. I don't think I
want to create a new user in FreeIPA, since it would have a uid/gid that
conflict with the locally defined account. However, I think I do need a
keytab for "daemon@DOMAIN". The ipa command doesn't seem to provide a
means of creating such a principal.
Should I work directly in kadmin to create the principal and export the
keytab? Am I even on the right track?
