The problem with this seems to be related to the fact that directory /var/lib/krb5kdc
is only readable for root.
$ ls -ld /var/lib/krb5kdc
drwx------ 2 root root 4096 Feb 5 2018 /var/lib/krb5kdc
If I chmod the directory to 711 it is possible to login via the browser.

The problem with this seems to be related to the fact that directory /var/lib/krb5kdc
is only readable for root.
$ ls -ld /var/lib/krb5kdc
drwx------ 2 root root 4096 Feb 5 2018 /var/lib/krb5kdc
If I chmod the directory to 711 it is possible to login via the browser.
I wonder
what was used to change it because krb5-server package installs
it as 755:
# rpm -qlv krb5-server| grep /var/kerberos/krb5kdc
drwxr-xr-x 2 root root 0 Aug 1 19:19 /var/kerberos/krb5kdc

I wonder what was used to change it because krb5-server package installs
it as 755:
# rpm -qlv krb5-server| grep /var/kerberos/krb5kdc
drwxr-xr-x 2 root root 0 Aug 1 19:19 /var/kerberos/krb5kdc
-rw------- 1 root root 22 Aug 1 19:13
/var/kerberos/krb5kdc/kadm5.acl
-rw------- 1 root root 458 Aug 1 19:13
/var/kerberos/krb5kdc/kdc.conf
I'm using Ubuntu 18.04, where it is /var/lib/krb5kdc and this directory has chmod
700.
That is true on Ubuntu 16.04 as well. Ubuntu 16.04 has freeipa-server 4.3.1-0ubuntu1
The Ubuntu 18.04 FreeIPA server installation (4.7.0~pre1+git20180411-2ubuntu2) places a
few files in /var/lib/krb5kdc (that's new).
So the question is: what was changed (in freeipa?) that it now wants read access of
/var/lib/krb5kdc ?

I'm using Ubuntu 18.04, where it is /var/lib/krb5kdc and this directory has chmod
700.
That is true on Ubuntu 16.04 as well. Ubuntu 16.04 has freeipa-server 4.3.1-0ubuntu1
The Ubuntu 18.04 FreeIPA server installation (4.7.0~pre1+git20180411-2ubuntu2) places a
few files in /var/lib/krb5kdc (that's new).
So the question is: what was changed (in freeipa?) that it now wants read access of
/var/lib/krb5kdc ?
We need access to the KDC's public certificate in case we are
dealing
with a KDC certificate issued by a local certmonger (self-signed) which
is not trusted by the machine.
You can read https://www.freeipa.org/page/V4/Kerberos_PKINIT for
details. A short version is:
--------
When you install 4.5 with --no-pkinit, the installer will generate
self-signed certificate for PKINIT. This certificate is only used and
trusted by IPA Web UI running on the same server to obtain an anonymous
ticket.
--------
That anonymous PKINIT is required right now to enable two-factor
authentication login to web UI because since FreeIPA 4.5 we cannot use
HTTP service keytab anymore: FreeIPA framework lost access to the keytab
due to privilege separation work we did (read
https://vda.li/en/docs/freeipa-debug-privsep/ for details)
Since your KDC PKINIT certificate might be issued by a local self-signed
certmonger 'CA' in case you are not using integrated FreeIPA CA, we have
to be able to trust *that* public KDC certificate when running 'kinit
-n', thus we need access to it.

Thanks for explaining this, not that I understand all of it. So, does this mean we
have to ask the Ubuntu/Debian maintainers to allow read access of /var/lib/krb5kdc ?
