Hello,
I am using Centos to host our FreeIPA servers. We have a CA-less setup.

I have upgraded to Centos 7.4 and FreeIPA version : VERSION: 4.5.0, API_VERSION: 2.228

The upgrade of both went off without any seen errors.

However, now I am getting the following messages on each server (12 in total):
"ERR - attrlist_replace - attr_replace (nsslapd-referral" messages

Firstly, are these messages real problems I need to deal with?
Secondly, if they are problems, how do I fix them? I have searched the internet and found lots of confusing mail threads, but no howto style document.

Thanks for any help.

Regards,
James Harrison
