Bug#365676: nscd: restart should cause a cache refresh

[Chris Adams <cadams@salk.edu>]

Package: nscd
Version: 2.3.6-7
Severity: minor


I noticed that nscd had cached an old copy of an LDAP group which we had
recently changed. After a few minutes of bad results I ran
'/etc/init.d/nscd restart' in the hope that it would cause nscd to
invalidate its cache but this didn't work. 'ncsd --invalidate group' did
- but it feels like the restart should have either simply purged the
cache or resulted in a background revalidation.

The TTL logic also seems to be a little imprecise - the group ttl is
listed as 600 seconds (nscd --statistics) but it was closer to 15
minutes before all of the clients I was testing with had updated.

(All testing was conducted using 'getent group')
