[Samba] Samba 3.3.4 - Win7 Latency with MS Office files

[John Goubeaux]

Ok, thanks for that detail on winbind usage.

Oddly my testing of the problem might have pinpointed the issue to be 
the fact that the Win7 is running on iMacs, YES!  AND there might be 
a driver related latency with the network card. Networking via the 
wireless card shows faster results.  Someone decided to buy a bunch 
of iMacs and run Windows on them and this is when we began seeing the 
issue. I will see.

With regards to a possible LDAP user retrieval issue I cannot see 
this changing  if one went from  WinXP   > Win7 on the client but the 
Samba  > LDAP mechanism has not changed at the server level where 
Samba is running.
