Hi

I've been having issues with the PPTP server and AD on my ClearOS box for a few weeks so I decided to reload it two weeks ago. The problem has persisted through the reload.

In a nutshell PPTP seems to timeout connecting to AD and users are unable to connect. They receive an "Error 734. The PPP link control protocol was terminated".

I've worked out that if I connect to the ClearOs console and go browse the AD users or groups through the account manager tab (I only use the browser interface to manage it) it refreshes and everything works and the users are able to connect. This will keep the VPN connections via the PPTP server working for a few hours.

If I go to the PPTP server without first going to the accounts manager tab it sits on "Connecting to Active Directory please be patient" status for ever. If I go to the groups then back to the PPTP server it connects to AD within a second or two.

Any ideas?

Try adding this to your /etc/samba/smb.conf in the global section:

winbind offline logon = yes

    Thanks Dave

    After several days of testing and users being able to connect without any further assistance or tweaking on my side I'm confident that has resolved the issue.

    A quick update.

    Users seem to be able to connect now without requiring any thing being done on the server side. Still early days, but should have a better idea after the long weekend.

    The PPTP Server still says "connecting to AD, please be patient" indefinitely however on the webconsol. This is not a major issue and something I can live with if the PPTP connections are working fine.

    Thanks for the help Dave.
