When I was writing the auth-pam plugin, I had problems dynamically linking the plugin to PAM unless OpenVPN itself was also dynamically linked to PAM (which I didn't want to do). Remember that PAM itself is going to dlopen, in turn, the actual PAM module. Combining dlopen with dynamic linking has got to be problematic when you are dealing with crosslinked dependencies. dlopening PAM from the plugin seemed to solve all the problems, and followed the approach that others took when accessing PAM from dynamic modules.
