...root ... but it's really not clear why this would be necessary if the username map entry is working. I added this on the server and it's not working either after restarting rpcidmapd. I also saw a red hat document that talked about adding to /etc/krb5.conf: [realms] ? EXAMPLE.COM = { ? auth_to_local = RULE:[2:$1/$2@$0](host/nfsclient.example.com at EXAMPLE.COM)s/.*/root/ auth_to_local = DEFAULT } ... but that doesn't seem to change the permission denied. Any feedback would be greatly appreciated. Thanks! Jason.

...getting NFS "root" access to work between a CentOS 7 client and CentOS 7 server? (AKA no_root_squash in /etc/exports). Finally, after a significant amount of effort, I figured that out last night.

I've looked at that in the past, but i was not interested in SSO so i've probably skipped.

[Apologies if this is an off-topic question; please direct me to a more appropriate place if so.] Using Kerberos/GSSAPIAuthentication, is there a way to centrally control/manage (perhaps using LDAP?) which user principals can log into what hosts/accounts? -- Jos Backus jos at catnook.com

...and of course when multiple domains come into play. So maybe someone knows of a valid workaorund, how to force kinit to automatically remove/strip DOMAIN prefix from e.g. DOMAINmyusername at MY.DOMAIN.COM and change it into myusername at MY.DOMAIN.COM? My understanding is that krb5.conf "auth_to_local" works the other way around, so it takes valid principal, and rewrites it so that it matches posix user and won't work in this case,as it's the other way round (posix user has to be translated into valid principal). My environment is: centos 7.4 OS samba 4.5.x is the AD DC samba 4....
