[Pkg-samba-maint] Bug#476667: bug is back wo nscd

[Christian Salzmann]

Hi folks,

from time to time nscd ceases work (I will write a separate bug report 
if I have investigated this more detailedly). Without nscd running, the 
segfaults of smbd are back.
The comment a bit earlier in this thread is still valid: In fact I 
should blame libnss_ldap for the bug.

ciao
Christian
