[Samba] Share name length limit?

[Stan.Pietkiewicz at statcan.gc.ca]

I just upgraded an HP-UX 11.23 IA 64 server to Samba 3.5.6, and one of
the shares would not work. It showed up in testparm as valid, but nobody
could connect to it. I shortened the length of the share name from 12 to
8 characters, and it now works. 

My pc is running Vista, and authentication is via our domain
controllers.

Is this a limit within Samba, or is it something being imposed by
Windows?
