Hi, First questions (sorry if it's obvious): - Do you have a valid token on the client? (obtained with kinit) - Did you import the keytab for NFS service on the server? - Did you put "domain = yourdomain.tld" in your NFS server config file? On your client? - Depending on your (ipa? nfs?) version you may have to enable weak crypto (I saw this everywhere but never had to do it for a reason I still ignore)
I'm far from being the most informed people on this list, but I think it may be the first things to check. Hope this helps, Regards -- Youenn Piolet piole...@gmail.com 2016-06-30 21:47 GMT+02:00 Joanna Delaporte <joannadelapo...@gmail.com>: > I need some pointers for getting NFSv4 to use krb5 authorization in my IPA > realm. > > My realm is new.
