Poptop - how to configure?

Dear All,

 	I am installing pptpd (aka poptop) on a 6.1 release box which 
is taking over the functions of a Debian box.  VPN is needed and 
Debian used pptpd for this, so I decided to follow suit.  However, I 
get errors that indicate that pptpd is not directing pppd to the 
correct options file.  Part of the debug output from pptpd is:

Dec 11 12:21:28 mail pptpd[54767]: MGR: Launching /usr/local/sbin/pptpctrl to handle client
Dec 11 12:21:28 mail pptpd[54767]: CTRL: pppd options file = /etc/ppp/options.pptpd
Dec 11 12:21:28 mail pptpd[54767]: CTRL: Received PPTP Control Message (type: 1)

Dec 11 12:21:28 mail pptpd[54767]: CTRL: pty_fd = 7
Dec 11 12:21:28 mail pptpd[54767]: CTRL: tty_fd = 6
Dec 11 12:21:28 mail pptpd[54768]: CTRL (PPPD Launcher): program binary = /usr/local/sbin/pppd
Dec 11 12:21:28 mail pptpd[54767]: CTRL: I wrote 32 bytes to the client.
Dec 11 12:21:28 mail pptpd[54767]: CTRL: Sent packet to client
Dec 11 12:21:28 mail pptpd[54767]: CTRL: Reaping child PPP[54768]
Dec 11 12:21:28 mail pptpd[54767]: CTRL: Exiting now
Dec 11 12:21:28 mail pptpd[54625]: MGR: Reaped child 54767

(I have also tried using /usr/sbin/pppd, with the same result).  The 
error from pppd indicates that it is trying to access the options file 
/etc/ppp/options, in spite of having:

 		# TAG: option
 		#       Specifies the location of the PPP options file.
 		#       By default PPP looks in '/etc/ppp/options'
 		#
 		option /etc/ppp/options.pptpd

in the pptpd.conf file.  I've tried symlinking an "options" to the 
"options.pptpd" file, but then it indicates that the ppp options, as 
suggested in the poptop distribution, are illegal:

 		refuse-pap illegal option

It's almost as if user-land ppp was being called instead of pppd. 
Anyone any ideas as to how I can get a better handle on this?  Thank 
you.

Cheers,

Rob Hurle
