This seems like it should be a common problem, but I haven't found any one else reporting it or a solution to it. I've built Samba4 4.1.7 from source on my Centos 6.5 64-bit machine. The machine is an Active Directory member, but not a domain controller. In general, all is working well. I have an application, however, that is looking for the 32-bit version of libnss_winbind.so and not finding it. The Samba4 build procedure created a 64-bit version, but not a 32-bit version. My research indicates that cross-compiling Samba is problematic, so just recompiling a 32-bit version doesn't look promising. Surely others are running into 32-bit applications on their 64-bit machines, soI feel like I'm missing something obvious. How are other people dealing with this problem?
