[pptp-server] Ok with pppd 2.3.8, problems with pppd 2.3.11

[Roberto Arcomano]

Hi all,
I have a little problem with my pptpd Linux client connecting with a NT
server.
If I use:
RedHat 6.2, Kernel 2.2.16, pppd 2.3.8 (patched) all is ok
but when I try with
RedHat 7.0, Kernel 2.4.0, pppd 2.3.11 (patched) I receive a problem like
this (from my syslog):

In my /var/log/messages I can see : Peer is not authorized to use remote
address 212.31.242.99

I don't know why, I patched my pppd 2.3.11 with 2 patches available.....

I need to patch my 2.4.0 kernel? I tried it but then I cannot compile it
cause source tell me there is a problem in pppoe module.
I saw that when I typed "make kernel" in pppd.2.3.11 patched I view that
it cannot overwrite 3-4 source files cause they are older than original
ones. I have to write them anyway?

Maybe it could be useful to know I connect to Netsystem (new Italian Sat
ISP) server to authenticate myself.
Thank you
