L2TP Server is not supported by Active Directory

Asked By 0 points N/A Posted on -

I am getting an error saying that “L2TP server is setup using CHAP, which is not supported by Active Directory” with our Sonic Wall LDAP. I recently sync it in my internal Active Directory controller. This problem started when I changed the user setting. Please help!

L2TP Server is not supported by Active Directory


Hallo Patricia Campbell,

I will suggest that you try running the Sonicwall on a non-DC and see how it behaves. In case you are trying to run it on two or more DCs then it is possible that it multi-homes the DC hence creating the problems.

The other thing that I will advise that you consider doing running the RRAS + PPTP on your version of DC that you are using, and then try forwarding the ports that are required through it. Although it may seem hectic, it will be a lot easier for you to manage access controls within the active directory in that manner.

See if that helps you out.
