[Samba] [PATCH] Workaround very slow nss_winbind, fix crash on the AD DC (particularly for backups)

[Philippe.Simonet at swisscom.com]

hi Andrew

the 
	interfaces = eth0, lo
	bind interfaces only = Yes

doesn't bring anything by me, always crash.

for the 2 other question I need some more time (never used valgrind,
and have to re-do the bisect ...)

Thanks and regards

Philippe
