...provide authentication and UID/GID mapping against a Windows 2008 R2 domain controller. I've been asked to get Kerberized NFSv4 working, but this problem occurs on mounts both with and without Kerberos, so I won't torture anyone with the Kerberos part. :-) ID mapping works: [joeuser at nfsclient ~]$ id joeuser uid=56055(joeuser) gid=6502(domain users) groups=6502(domain users),1000001(BUILTIN\users) Mounting directories -o sec=none works: [joeuser at nfsclient ~]$ sudo mount -t nfs4 -o proto=tcp,port=2049 -o sec=none nfsserver.example.com:/testdir /mnt [joeuser at nfsclient ~]$ ls...

Hi again, I just started to debug things on the samba4 side: When trying to mount the Windows NFS share, I get the following error on the samba4 dc (just grepping for nfs in the logs): auth_check_password_send: Checking password for unmapped user [S5DOM.TEST]\[nfs/nfsclient.mydom.test]@[] map_user_info_cracknames: Mapping user [MYDOM.TEST]\[nfs/nfsclient.mydom.test] from workstation [] auth_check_password_send: mapped user is: [MYDOM]\[nfs/nfsclient.mydom.test]@[] expr: (&(sAMAccountName=nfs/nfsclient.mydom.test)(objectclass=user)) sam_search_user: Couldn...

Hi all, I believe that this behavior is caused by the ``intr'' (-i) option to mount_nfs(8). As noted by Stephan Uphoff in PR/79700, he does not recommend use intr option. After remove the option, the dd works well. Sorry for the noisy :-) However, I think some warnings can be added to mount_nfs(8) about the usage of intr and its consequence. So this won't be happened again.

Hello. I thought rc used to start nfsiod if you set nfs_cilent_enable back years ago. Now, on my 7.1-RELEASE machine, it sets up a couple of sysctls in /etc/rc.d/nfsclient script but not nfsiod. Is nfsiod obsolete by now? It is still on the system; does it still improve nfs performance? Thanks, Hiro

...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.
