+glibc (2.5-5) unstable; urgency=low
+
+ Since this release, hosts caching in nscd is off by default: for some of
+ the libc calls (gethostby{name,addr}* calls) nscd does not respects the
+ DNS TTLs. It can lead to system lockups (e.g. if you are using
+ pam-ldap and that you change the IP of your authentication server) hence
+ is not considered safe.
+
+ See debian bug #335476 and how upstream answered to that in
+ http://sourceware.org/bugzilla/show_bug.cgi?id=4428.
