1. Principal accused of
   covering up sex scandal

Why in the world would a principal ever cover up a sexual assault at
school? Prosecutors are offering a shocking theory:

2. What’s more important
   than high test scores?

So many schools are devoting a lot of time and energy to having their
students do well on standardized tests. But what we really need is
curriculum time devoted to this, a writer says:

3. When students struggle, how
   soon should parents be called?

In this district, many teachers are willing to reach out to parents
when students are on the road to failing a class. But others cite a
reason for not doing so as quickly:

Bug#485282: nscd: Change default cache setting to work better with roaming laptops

I've a very strange feeling when reading this bug report.

I'm under the impression that the proposed nscd config is something
that will more or less allow to do offline login without nscd having
being designed for that. So, I expect that nasty corner cases will
occur (deleted account being still valid for 30 days, ...)

For me, what is wanted is a local slave ldap server with all the
required protocol needed to work while (and recover after) a network
failure. Ie, a cache (nscd) should be used to cache data and get better
performances, not to take place of a broken ldap server.

If the classical ldap server is too heavy for this task (or does not have
this feature), then working on this part (a new small dedicated ldap
replicate server) is probably the better long-term solution.

  Regards,
Vincent

I wonder if this could be handled sanely with a debconf question.

Also I suspect that mimicking the behavior of other operating systems
could be useful for the more generic case.

The reported size (0x000139e0) is much larger than the actual binary size.

Bug#579917: mkhomedir segfaults within ld.so on startup

2010-05-02 Thread Andreas Barth 
Package: libc6
Version: 2.7-18lenny2
Severity: grave

Hi,

the following happens when trying to run mkhomedir_helper. This
happens with any glibc version, i.e. also in testing and unstable
(that's how I found out). mkhomedir_helper is only available in
testing and unstable, but well.

I'm not convinced if the libc6 is the correct place to report this bug
to, but having this bug will prevent the release of Debian on mips*
(as DSA needs to have mkhomedir available). Please also note that this
programm wasn't part of lenny, as the pam module was restructred
recently. It however does work on i386.

Something like this would make that possible, as long as the
/etc/default/nscd fil is not included in the nscd package.

Bug#485282: nscd: Change default cache setting to work better with roaming laptops

2010-05-02 Thread Petter Reinholdtsen 
Great to have more feedback on this issue. :) I hope someone with
knowledge and experience on offline operation of a networked laptop
can share their view. :)

[Marco d'Itri]
> And what about the increased memory usage on large systems?

What increased memory usage?  I got nscd running on a laptop connected
to the university of Oslo with ~6 users and ~6000 groups, and do
not see large memory usage by nscd.

Well, at least here at the university, laptops are becoming the normal
setup, and having offline authentication and operation work is
becoming a vital requirement. :) If bugs #485282, #566718 and #568577
are solved, it would be a simple matter of installing nscd and
libpam-ccreds to get it in Debian. :)

> What about deleted user? Deleted users still existing for 30 days
> could be a nasty security issue.

You seem to be arguing only against the increased positive time to
live.  Is that the case?

For offline operation, I suspect the "reload-count unlimited" setting
is the most important one.

If increased timeout is left out from the default configuration,
please implement support for sourcing /etc/default/nscd and allow a
policy compliant mechanism to replace the configuration file used by
nscd.

Happy hacking,
