Hi, i've been spending quite some time on figuring out how to setup samba to access user data on a NFSv4 share that is secured by kerberos. User home directories reside on this network filesystem. kdc01.fqdn:/users/ on /home type nfs4 (rw,sec=krb5,addr=w.x.y.1,clientaddr=w.x.y.2) setting up samba for kerberos, i followed these descriptions: https://help.ubuntu.com/community/Samba/Kerberos security setting: "security = user" (i checked out the ads setup, too, but with the same result) My current setup is working when 'kerberos security' is switched off for the NFSv4 mount. Therefore i think kerberos authentication is working. The Problem is: Samba should open a pam session, getting a kerberos ticket for the user to access the data. Which configuration steps are required to accomplish this? Or is it totally insane to do that? I did not want to setup an Samba share on the actual File Server. Is this the only way to do that? Cheers, rfs
