Hmmm, I am not sure that winbindd is the culprit here.

In any case, NetBIOS names are resricted to 15 characters. Always have 
been. The 16th character has always been the type char, since 1984 when 
IBM defined the protocol.

When joining a domain, the client joining needs an account on the server 
with a $ on the end. This accounts for the 14-char restriction. 

The question is, do Windows PDCs allow clients with 15-char names to join?

If they do, then Samba should re-examine the decision. If they don't, then 
you will have to reduce the length of the name.
