LTI-Basic Authentication with moodle

Hi,

We're trying to set up LTI-Basic Authentication with moodle, and have configured the following in authen_LTI.conf:

$LTIBasicToThisSiteURL="http://servername.edu/webwork2/coursename";

and

$LTIBasicConsumerSecret = "mysecret";

I'm not sure how to configure the consumer key in authen_LTI.conf, and on the moodle end, I left it blank.

The last thing I believe I have to configure is the user parameter to be sent by the LMS. We have the same usernames on moodle and webwork, so I believe this should be the username. I'm not sure how to configure this part in authen_LTI. I tried the line:

$preferred_source_of_username = "username";

but get no automatic login to webwork - I just get to the webwork course login page, and must enter the userinfo manually.

Any help appreciated.

Lars.

....no answers....

Does this mean that nobody has tried to authenticate to webwork from moodle using LTI?

I had partial success in that I was able to authenticate from my moodle course directly into Wheeler's webwork course (as described in the wiki) without having to provide username/password by using the External Tool in moodle....But I can't get it to work with my own webwork course, and I'm not sure what the issue is.
