FreeIPA and XCP hosts

[Christian Reiss]

Hey folks,

I am running into a bit of trouble installing the FreeIPA Client on 
XCP-NG (https://xcp-ng.org/, Fork of XenServer). They are based on CentOS 7.

Running "yum install --enablerepo=epel,base freeipa-client" results in this:

--> Running transaction check
---> Package ipa-client.x86_64 0:4.6.8-5.el7.centos will be installed
--> Processing Dependency: ntp for package: 
ipa-client-4.6.8-5.el7.centos.x86_64
Package ntp-4.2.6p5-29.el7.centos.2.x86_64 is obsoleted by 
xcp-ng-deps-8.2.0-10.noarch which is already installed
---> Package python-tdb.x86_64 0:1.3.18-1.el7 will be installed
--> Finished Dependency Resolution
Error: Package: ipa-client-4.6.8-5.el7.centos.x86_64 (base)
            Requires: ntp
            Available: ntp-4.2.6p5-29.el7.centos.2.x86_64 (base)
                ntp = 4.2.6p5-29.el7.centos.2

any chance of getting this resolved in any way?

Thanks for your kind help :-)

The client install sets ntp to sync to the pool of ipa servers. It's going to require an installation of ntp for all of the installation scripts to run.

IMHO this is a packaging issue on the XCP side. I'd ask them why they
prevent ntp from being installed.

Time is very important for Kerberos and TLS.

In the semi-distant past some virtualization solutions had a rather big
problem keeping proper time. Maybe this conflicts dates back to that.
