Hi Rowland,

Just a stab in the dark: with the "old" winbind-on-DC approach (4.0, 
4.1) you had to use the libnss_winbind.so that was built during compile, 
which in my case involved symlinking the shared objects into the /lib64 
directory (on centos6). This was not done by "make install".  Is it 
possible you are using the "old" libraries still?
