Succes, well sort off

This patch works for me as well. I can no longer crash winbindd by  
running
     getent passwd

However my auth.log file still contains
     write to socket failed!

But just a few seconds later it appears to be working, but it does  
not work.

And the user complains that subversion update through apache2 through  
pam authentication through winbind to win 2003 server does not work.
TortoiseSVN does no longer ask for username/password.

A restart of winbindd did not help, i had to restart apache2 as well  
before it would work.

After this restart i tried repeating the error by running     getent  
passwd    but i can
nolonger get     write to socket failed!    messages in auth.log.
