How do I verify that sshd is compiled and linked with PAM support.? No really how is this done?  There doesn't appear to be a command line switch like a -V or something like that, that would tell what I need to know.  Luckily I am running Redhat and can look at the SRC RPM's (openssh-server) spec file ...
