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

["Howard Wilkinson" <howard [at] cohtech.com>]

I have found out what was wrong and have a fixed patch set for solaris. I will 
push this to the bugzilla as part of the bug patchset 
http://bugzilla.padl.com/show_bug.cgi?id=412
 
The problem is that the new NSCD interface aliases the use of the buffer that 
it passes and the code was overwriting the results it was generating. I have 
added code that detects this and manages the buffers. I have managed to test 
the passwd and group maps so far but unless there are typos, or I have got the 
string format wrong then all of the other maps that are implemented should work.
 
The one map I have not done yet is the netgroup map. I will tackle this in the 
next few days.
 
The code has been compiled for Linux and tested there as well and this still 
works. I may have broken other ports and this will need to be checked out, but 
I do not have facilities to do that at present.

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.
