It looks like foobar is being mapped to root. There are several ways
that this can happen.

My first suspect would be that force user = root has been put in the
smb.conf file by a gui, and the change only took place after the
restarting of samba. (only because this happened to me once.)

My second suspect, (which is more likely) would be that smbpasswd was
munged during the upgrade.

A third possibility is that the user shows up as

admin users = foobar, admin, troy

For more useful help, the entire smb.conf file would probably need to be known.
