RE: [nssldap] Solaris 10 update 5 - nss_ldap makes nscd dump core



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.
 
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.
 
Howard.

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.
