Please file a bug report on https://bugzilla.samba.org with clear information 
regarding what is wrong with the documentation. Please provide an example of 
how we can reproduce the problem and all information that you can offer to 
help correct the defect.

I have tried to check this on several Linux systems and am unable to find a 
problem with the default installation method. The default installation method 
matches what is in the documentation.

The libnss_winbind.so library needs to be in the standard place that is 
searched for by the Name Service Switcher (NSS) on your system. It needs to 
be linked to the version of the nss libraries that you operating system is 
designed to search for.

On Linux  the correct location for this file, together with its symbolic link, 
is in /lib. There is no benefit at all in adding links to the /usr/lib 
directory.

Please help to clear up whether or not the documentation really does need 
updating or if in fact your claim that it is incorrect is in itself bogus. 

Winbind does not use the libnss_winbind.so library - that is called only by 
NSS and therefore the location and linkage of the libnss_winbind.so library 
can not have anything to do with why your winbindd may have crashed.
