Comment 40 for bug 1644428

This was finally fixed properly upstream with this massive patch set https://bugzilla.samba.org/show_bug.cgi?id=14780 for Samba 4.16. A very good reason to upgrade to this release where possible.

By building a properly static (in terms of samba libs at least) pam_winbind.so, there should be no more unresolved symbols.
