[Freeipa-users] Warning about session memcached servers from ipa-replica-manage

[Roderick Johnstone]

Hi

I'm getting the following warning on RHEL7 ipa servers 
(ipa-server-4.2.0-15.el7_2.6.1.x86_64).

$ ipa-replica-manage list
ipa: WARNING: session memcached servers not running
aaa.xxx.yyy: master
bbb.xxx.yyy: master

Can someone advise please on what the session memcached servers are for 
and how to get them running, assuming they are worth having.

Thanks.
