Description of problem:
With the configuration below nscd seems to remove user info after a period of
time (noticed both after 5 minutes and after 15 hours). I did something like
this to test (using LDAP as info source):
service ldap start [succeeds]
service nscd start [succeeds]
id testuser [succeeds]
ls -l ~testuser [succeeds]
service ldap stop [succeeds]
id testuser [succeeds]
ls -l ~testuser [succeeds]
<wait, retry, wait, ...>
id testuser [fails]
ls -l ~testuser [fails]
It seems that the time after which entries get removed is more or less random
making it hard to identify any clear occurances causing this.
This is important to allow laptops to work when not connected to the home
network.

I was able to reproduce this easily on Fedora 10 with all updates as of
2009-03-10 installed, including:
root@localhost:~# rpm -q nscd
nscd-2.9-3.i386
I will attach from Fedora 10 test /etc/nscd.conf, /var/log/nscd.log, and steps
done in a terminal.
