Hullo, I run a network of (amongst other things) FC5 desktops which connect to our fileserver using CIFS. The fileserver is running FC2 with smbd version 3.0.7-2.FC2, and we use pam_mount to mount per-user network shares on the desktops at login time. With the /etc/security/pam_mount.conf and /etc/pam.d/system-auth-ac files edited appropriately, this works fine on an unpatched FC5 install; however after a full yum update the directories won't allow reads: $ ls /mnt/shares/share1 ls: /mnt/shares/share1: Operation not supported Rolling back to the original kernel (i.e. from 2.6.18-1.2200.fc5 to 2.6.15-1.2054_FC5) makes the problem go away. I couldn't find any help for this by Googling around - is this a known issue? The samba-client version is 3.0.23c-1.fc5. Any help gratefully receieved, Chris
