[pptp-server] require-mppe on pppd-2.4.1

[George Vieira]

looks like the 2.3.11 patch does seem to patch OK against 2.4.1

Now for the ultimate test.... compile and use it..

[root at firewall ppp-2.4.1]# patch -p1 < ~georgev/require-mppe.diff 
patching file pppd/ccp.c
Hunk #2 succeeded at 121 (offset 17 lines).
Hunk #3 succeeded at 468 (offset 13 lines).
Hunk #4 succeeded at 1293 (offset 17 lines).
Hunk #5 succeeded at 1467 (offset 13 lines).
patching file pppd/ccp.h
patching file pppd/mppe.c
Hunk #1 succeeded at 227 (offset 1 line).
patching file pppd/mppe.h

Well starting the tunnel only gave me "Input/Ouput" and wouldn't start.. I
removed the require-mppe and it's working again..

something weird...
