View Full Version : [all variants] NTLM authentication issues

December 16th, 2010, 08:11 AM

I am in the process of building a filter for our internal office network. Specs are as follows:
Ubuntu 10.10
Samba 3.5.4
Squid3 3.1.6-1

I have installed and configured the server to a tutorial showing how to setup dansguardian, as well as setup NTLM authentication to create multiple groups with different levels of the filter.

i am having issues with getting those groups to work, as NTLM authentication seems to be failing. we have a W2K8R2 DC, which upon researching has been causing some issues with NTLM authentication.

i get the following when trying to test the authentication:
plaintext password authentication succeeded
challenge/response password authentication failed
could not authenticate user administrator with challenge/response

the server has successfully been joined to the domain.

any suggestions will be appreciated.
