Probable shared library conflict.

This is useful, now the question is what libraries do PAM and/or the
system nsswitch bring in? Please post the contents of /etc/nsswitch.conf
(or FreeBSD equivalent). It may be the case that nsswitch or PAM loads
an incompatible Berkeley DB or an incompatible SASL library.

Multiple incompatible implementations of the same interface within
the same address-space are a problem on all systems. The degree of
the damage varies, but the problem is never removed so long as dynamic
loading is employed. My $0.02 is that all use of dynamic loading are
design failures that are correctly addressed via IPC.
