I followed these instructions to enable kerberos within my realm/domain.
My FreeIPA, NFS server and my NFS client is CentOS 7.4
I’m completely stuck in that when I mount the NFS share I get
Sudo mount -o sec=krb5p share.example.com:/data/shared /mnt/shared
“mount.nfs: access denied by server while mounting share.example.com:/data/shared”
My /etc/exports file
/data/shared 172.16.0.0/24(sec=krb5p, rw, ...)
On my nfs server /var/log/messages all i see is
rpc.mountd: authenticated mount request from 172.16.0.23:819 for /data/shared (/data/shared)
If i remove the “sec=krb5p” from the mount and the exports file it mounts just fine.
I'm having an issue with OTP when logging into a vpn server that is a client of FreeIPA. I can login with no issues when OTP is disabled.

Any help would be greatly appreciated. Any other information that you may need, please feel free to ask. I've read multiple threads, some have gotten it to work without posting answers, some have not and has stated openvpn does not support multiple prompts.
We have noticed some behaviour that we are trying to work out if it is
expected or not (or if this is an SSSD thing). We have a pair of FreeIPA
replicas running on CentOS 7 (v4.5.x), with various CentOS 7 clients.
Most clients aren't actually enrolled in FreeIPA, but are configured with:
id_provider = ldap
auth_provider = krb5
Authentication works as expected, plus password changes etc. However, if
a user has added a public key to authorized_keys, the status of the
password is not considered and at no point is a user prompted to change
their password. More importantly, if a user is disabled in FreeIPA, they
are still permitted to login using their SSH key.
I have checked the behaviour on a client that is enrolled, and it is better
(disabling a user does prevent access), but it still does not give any
indication about failed passwords.
Under most circumstances this wouldn't be too much of an issue, but we make
use of one application for remote access that does not know what to do with
an expired password, and instead just presents 'authentication failed'.

The system so far seem healthy. Did these file permission had a
stricter access that was relaxed later? I have never attempted to
change them, at least impicitly
Just because we can and a Rapsberry Pi 3 is cheap, I'm trying to
install a FreeIPA replica on Fedora 29 ARM. It looks like the Raspberry
is a bit too slow for default installation settings:

I did change the "startup_timeout" in /usr/lib/python3.7/site-
packages/ipalib/constants.py and /etc/ipa/default.conf but it doens't
seem to be enough.
About a year ago I did a really, really stupid thing. I updated IPA on one CentOS 7 host, then before being really sure things were working, I did the replica. Turned out the first upgrade only 'mostly' worked[*], meaning both hosts are now partially wrecked :S
The good news is, DNS and PKI seems mostly in-tact and functional (why I haven't done anything for a year). The bad news is, the web interface and API-access (ipa cmdline) is non-functional. Meaning I have no way to maintain the setup, add new replicas/hosts, etc. :(
Both kerberos and ldapsearch are working, so I'm wondering if there's a way I can "save" my DNS and user/group/kerberos records, to make a re-build/re-install less painful? I don't have anything worth saving PKI-wise.
[*] The damage was caused by running out of disk-space after the package install, while the upgrade or schema-update script was running. I'm not above trying to repair the API, but so far my attempts have all been fruitless. I tried 'yum reinstall' and manually running the upgrade scripts. The damage seems to be inside the databases, since restoring from backup also restores API-breakage.
So I had a running replica on CentOS 7 LXC which started giving me trouble,
so I decided to rebuild it.
Now, when running ipa-replica install I get:
2018-11-04T20:12:20Z DEBUG stderr=pkispawn : ERROR .......
subprocess.CalledProcessError: Command '['sysctl', 'crypto.fips_enabled',

2018-11-04T20:12:20Z CRITICAL Failed to configure CA instance: Command
'/usr/sbin/pkispawn -s CA -f /tmp/tmpyZ34z1' returned non-zero exit status 1
, which seems to cause this to fail. Googling around, I find this thread:
, where apparently two bugs were filed to fix this- and they were fixed.
Are they supposed to land on CentOS 7?

I consider to deploy FreeIPA in my home network.
In this network I run several servers and workstations with both Linux and Windows.
In addition I have setup some Webservices running in containers (LXC).
I have only one public IP and manage the (privately hosted) Webservices with a reverse proxy.
The network architecture includes several networks, e.g. LAN, DMZ, ...
All networks are secured by relevant iptables roules.
I want a central user management strong security management.
This is included in FreeIPA.
In addition FreeIPA includes some network related features, e.g. DNS.
And here starts my problem.
Currently I manage the DNS of my public domain with the domain provider.
If I install FreeIPA I need to shutdown the DNS management with the domain provider and manage this by myself.
Can I shutdown this DNS service before starting FreeIPA installation w/o impacting DNS resolution to my domain?
What happens if FreeIPA is down? Should there be any redundancy?
I have executed script setup.sh from package "freeipa-letsencrypt".
The installation finished with this error message:
ipaplatform.redhat.tasks: INFO: Systemwide CA database updated.
ipalib.backend: DEBUG: Destroyed connection context.rpcclient_140228802354200
ipapython.admintool: INFO: The ipa-certupdate command was successful

certutil: Server-Cert is neither a key-type nor a nickname nor a key-id: SEC_ERROR_IO: An I/O error occurred during security authorization.
What's causing this error?
And how can I fix this?
The file "httpd-csr.der" in working directory (in my case /etc/ssl/ipa-le/) is 0 bytes. Therefore I conclude that the installation was not successful.
