You know, I can probably fix this in the smbd server code by detecting
a UNIX client and relaxing the "invalid character" checks for things
like : etc.

Here is the current list of invalid characters we check for Windows
clients.

*\\/?<>|\":

and here are the reserved names we disallow for Windows clients

"AUX", "LOCK$", "CON", "COM1", "COM2", "COM3", "COM4",
  "LPT1", "LPT2", "LPT3", "NUL", "PRN"

So for a Linux client I can relax this significantly...
