Most of our FreeIPA client nodes are Ubuntu 14, 16 and some 18. We have a fair number
where I am unable to use SSH authentication because the server refuses the key.
The same user/key works fine on other nodes.
I have checked to the best of my knowledge the files and compared them to a node that
works and can't find any differences.
/etc/nsswitch.conf
/etc/sssd/sssd.conf
I don't understand the nuances of FreeIPA to know where else to look. Can anyone
suggest what else I can look at to troubleshoot what is going on? Every user experiences
this on different nodes.
Thanks!
