PPTP VPN errors, 10.7

Got the same problem here.

I tried re-ordering some of the entries you have to put into the serveradmin command which resulted in having more of them being accepted. The only one that was never accepted

was vpn:Servers:com.apple.ppp.pptp:PPP:AuthenticatorProtocol:_array_ index:0 = MSCHAP2.

So I am still stuck at the same error messages you see.

James,

I changed the com.apple.ppp to my domain.

My input was:

sudo serveradmin settings

Password:

vpn:Servers:net.domain.mms.pptp:enabled = yes

vpn:Servers:net.domain.mms.pptp:IPv4:DestAddressRanges:_array_index:0 = 10.0.0.64

vpn:Servers:net.domain.mms.pptp:IPv4:DestAddressRanges:_array_index:1 = 10.0.0.90

vpn:Servers:net.domain.mms.pptp:PPP:AuthenticatorProtocol:_array_ index:0 = MSCHAP2

vpn:Servers:net.domain.mms.pptp:PPP:AuthenticatorPlugins:_array_index:0 = DSAuth

vpn:Servers:net.domain.mms.pptp:PPP:MPPEKeySize40 = 1

vpn:Servers:net.domain.mms.pptp:PPP:MPPEKeySize128 = 1

ctrl+d

The output I recieved was:

};

};

};

}

mms:~ admin$

The connection fails with the message:

The PPTP-VPN server did not respond. Try reconnecting. If the problem continues, verify your settings and contact your Administrator.

I am trying to figure out how to determine if the server is running. Any ideas?

James

Found the command to check the vpn settings.

sudo serveradmin settings vpn

Here is another thread on the subject:

I got it working now. Don't ask me how I did it exactly. I was shuffeling around the entries to the serveradmin until each and everyone was accepted. It seems you need to add the entries in the right order. The pptp enable must be the last one because that will always return to off unless all other settings are already set up.

Hi,

I have the same issue after upgrading from SL to Lion Server. I think the problem is with:

Also the workaround with vpnaddkeyagentuser is not working for me beacuse I'm not able to use my admin user when it asks for it.

I'm using this as home server so I never really used OD. Just after upgrade to Lion I deleted some users and created them again thru the new Server.app. So I thought the OD admin will be my local admin. I was looking into the LDAP tree and found user diradmin, but I'm not sure if I can change his password.

Yes can you please post the order you used to get it working?

Thanks!

I don't remember the exact order, sorry. I made sure that I always set those options first that would be needed by the options I entered after that. e.g. I enabled the PPTP service at the very end after all other settings were set because else the service would not start.

You have to play around with this and use the order that makes the most logical sense. What also helps is setting the commands in increments (one command, exit utility, start utility, next command, exit utility... you get the idea).

Hello James!

You saw the typo in HT4748?

There is no blank at vpn:Servers:com.apple.ppp.pptp:PPP:AuthenticatorProtocol:_array_index:0 = MSCHAP2

between "array_" and "index".

But for me this does not help, either. Still no luck.

Stopped vpn

set things up as mentioned in HT4748

removed vpn-key-user with directory editor

created a new one with vpnkey....

started vpn

Still the same problem :-(

Bye

Seems to just be broken. I would bet you could turn encryption off and it would work fine. Seems to be a problem when using OD, likely works without OD but that's useless. As is using it without encryption.

Has anyone tried Apple tech support?

So, I called and opened up a case. Turns out I am not the only one (as you may have guessed). The response I got is that it is a known issue with no current useable workaround (disabling encryption is not useable). But, they are working on it. I volunteered to be a tester should they come up with a patch, etc.

Fixed in 10.7.3 dev build

Copy /usr/sbin/vpnd

to your 10.7.2 install

this fixes the pptp auth issue

I need to clarify.

replacing vpnd does not fix the MPPE issue described in this thread

but does fix the CCP issue a described in this thread:
