[Samba] methods to synchronize tdb files between hosts

[John Stile]

I use winbind+AD for single sign-on to many Linux machines,
and the Linux hosts automount home directories on one Linux file server.
I am faced with a need to synchronize the *.tdb files on the file server
with all the Linux machines for consistent UID-to-loginID mapping.

Has this been tried by sharing the /var/lib/samba/ over nfs with the
other servers?  Are there any pitfalls?

Has this been tried by a regularly scheduled copy over the network?

Does anyone have a how-to or notes for a better approach?
