Subject: RE: [nssldap] Solaris 10 update 5 - nss_ldap makes nscd
dump core
I have another version of the patch to the bugzilla. This now uses
heap allocation rather than stack based. The stack was failing when
large groups were being used.
I have also added a piece of conditional compilation to remove the
work round for a bug in the openldap library when not being compiled
against openldap. This was making the sun native library fail.

Subject: RE: [nssldap] Solaris 10 update 5 - nss_ldap makes nscd
dump core
I have pushed another patch out to the bugzilla which now seems to
work on Solaris 10 and on Linux. I have run some extensive tests on
Linux and some limited tests on Solaris and it all seems to be
functioning fine so far.
I have made the decision to use stack allocation for some buffer
space that is needed when called from the Solaris nscd (this code is
done at runtime so will also happen on Linux if the interface ever
goes that way) and have made room for a stack checking function
(which I have yet to work out how to do).
I may choose to replace this with heap allocated data but will wait
for experience reports before deciding this.
Any experiences using this code would be most gratefully received.
Luke any chance of getting this intergrated into the mainstream
release?

Matthew,
I have a partially working implementation. NSCD is calling into
nss_ldap and getting the results back but is not returning the
result back to the getent call. So any pointers would be gratefully
received. I am trying to get this working for a deployment in the
next few weeks so if you have patches I can try that would be very
helpful.
We're going to post the source code today or tomorrow without
encumbrances and you are free to use it as-is or extract and use
whatever information you find useful (well, attribution would be
nice). I'll follow up with a download url when the code is available.
Do you have any idea which hat dropping makes NSCD stop working?
Reading the OpenSolaris code it does look as though there is a lot
of dependencies on a stateful interface in the NSS2 facilities.
Unfortunately not. I do know that merely updating the time stamp on
the nsswitch.conf file will cause NSCD to start working again (until
it gets tired again). We are as puzzled as you are.
Cheers,
-Matt

We've developed the SPARKS changes needed for Sol10u5 and later (this
is why nscd was dumping core), but nscd on Sol10u5 and later seems
very fragile and stops working at the drop of a hat. We've been
sitting on the code until we've worked this out, but that's been
going
very slowly. We would be happy to share what we have if anyone is
interested.

This is very much a work in progress - I am focussing on getting
getent passwd working with nscd running. If I can crack that then
the other changes are 'obvious'.
This has been compiled on both Sparc and x86 Solaris 10, but only
tested on Sparc so far.
Let me know how you get on!

Hello Howard,
Any help that you, or anybody else can give to fix this problem
will
be gratefully received. This has been a problem for over a week
now.
could you please send me you're build instructions and patches. I'll
be
happy to help track down the getent bug. I'm also interested in
providing a backport.
Thomas
