[Freeipa-users] Reinstall ipa client, problem with old CA

[Dewangga Bachrul Alam]

Thank you Martin,

Yes, the IPA Server was built on CentOS 7.1. But, some client still
using CentOS 6.x, but I have plan upgrade them to 7.x.

Is it gave a problem if some client still on CentOS 6.x and the IPA
Server built on CentOS 7.x ?
