Configuring OVT with the --without-pam option will implicitly disable vgauth.

When no vgauth option is given alongside -–without-pam, a warning
is displayed with a message “Building without PAM; vgauth will be
disabled.”.

When -–disable-vgauth is supplied alongside –-without-pam, no
warning or error message is displayed.

When -–enable-vgauth is supplied alongside -–without-pam, an
error will be thrown and the configure stage will be aborted with an
error message “Cannot enable vgauth without PAM. Please configure
without --without-pam or without --enable-vgauth.”
