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

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

Hello Thomas,
 
thank you for the information. Can you comment on why you chose to statically 
link the libraries that nss_ldap calls in? We have been trying to use dynamic 
linking and keep being told that the routine gss_krb5_ccache_name does not 
exist, despite the fact that we can see it in the mech_krb5.so.1 library file.
 
As we are linking the 265 release with my patches attached then there is still 
the possibility that we have a link time error, possibly caused by my having to 
include an interface spec for the gss_krb5_ccache_name in the source as it is 
missing from the Solaris 10 header files.
 
Howard.

Hello Howard,

nothing that I'm aware off. But The native ldap client of Solaris is
very usable these days (Solaris 10 Update 8).

In my experience the code doesn't get called if a) nscd is running or b)
your shared object doesn't find it's libraries. You can check very
easily using:

ldd /path/to/nss-ldap.so

I have something that links the dependencies static using the native
compilers:
