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
