I was used to integrate some linux client in my samba network mounting homes with 'unix extensions = yes', and works as expected, at least with some old lubuntu derivatives. Client side i use 'pam_mount'. Now i'm working on a ubuntu mate derivative, and i've not found a way to start the session properly in CIFS. If i create a plain local home (pam_mkhome), session start as

(mount -t nfs -o nfsv4 ....) and btw. Is forcing mount to use -sec=krb5 (with -sec=sys:krb5:krb5i:krb5p in /etc/exports) also 100% sure? because it mounts and doesn't give ticket for nfs/nfsserver. So, I guess if -sec=krb5 is not available, it mounts with -sec=sys, right? With -sec=krb5:krb5i:krb5p in /etc/exports it doesn't mount. I am wondering if you force -o nfsv4, it wouldn't m...

Hi Louis, Thanks for your message. However, I already have NFS working completely. I'm only trying to work out root NFS access on the client.? I tried your NFS translation fix via idmapd.conf? but that isn't working for me. I've discovered that's because CentOS 7 is using gssproxy so apparently your fix won't work. The fix from Red Hat (adding some lines to krb.conf seen in my

Hi all, I am testing different setups for Samba home share mounts via the CIFS protocol on Linux clients with and without Keberos security (both krb5 and krb5i). I am experiencing some strange behaviour in case of Kerberos authentication: In case of mounts (by root or the user itself) without Kerberos security (only NTLMv2 authentication), local root and the owning user on the Linux client is granted read and write access for the files within the mou...

Hi everyone, I have a samba DC, let's call it dc1.ad.example.com. I have two members of the domain - server1.ad.example.com and server2.ad.example.com.?? They are not running smbd and winbind. Instead, they are running SSSD with AD backend. I want to create an NFSv4 export on server1.ad.example.com and mount it on server2.ad.example.com (say, sec=krb5). I found some instructions online

Hello, I've been doing some extensive troubleshooting with respect to some issues mounting CIFS shares on a Windows box via Kerberos. We're using the command: /sbin/mount.cifs //whatever/whatever /whatever -o sec=krb5i This should mount the share using Kerberos & Packet-signing by using the cached credentials of the user executing the command. With judicious use of strace, it seems that cifs.upcall makes the assumption that the Kerberos credentials will be present at /tmp/krb5cc_UID, however, this is not...

...wever, non-domain joined clients (various Linux systems) cannot use username/password authenticate to map the network drives - they always get permission denied. If I go and get Kerberos tickets for the problem clients (using kinit and friends against the domain controller), mount.cifs with sec=krb5i works. But we cannot get sec=ntlmsspi to work. This was working on an older server (CentOS 6.10, Samba 3.6.23), and I think the key is that the "map untrusted to domain" option was deprecated and eventually removed in Samba 4.8. Otherwise, the configurations between the older and new...
