Just in case, as I did, you think of running a mixed windows/linux network using a samba PDC then here’s something to be aware of. When mounting the smbfs filesystem from linux, you will get CIFS extensions. Great - your uids will be the same on server and client. However, winbind will generate you a random uid when it authenticates on the PDC. What joy!

Given that these two utilities are from the same project, you think they would play nice.
