Hi Colin, sorry for the late reply.

If the 401 error shows up in Blackboard's access log (as a result of LAMS contacting Blackboard, not your own manual entering of the URL), then I'd check that the server id and server key entered in both LAMS' ext_server_org_map table and Blackboard's LAMS module configuration settings are identical (HTTP 401 represents an authorisation error).

Another thing you can do is, when you access LAMS from Blackboard and it doesn't work, go to your Blackboard access log, grab the UserData URL such as

/webapps/lams-plglamscontent-bb_bb60/UserData?uid= __SNIP__

and paste this into your browser (with the full parameters at the end, and your blackboard domain at the beginning of course). If you get a plaintext response containing username, firstname, lastname, and email, then there may be a bug in the LAMS code. If it responds with a 401 error, then it's most likely an incorrect serverid/key.

I'm just going to make a note of this - the module should probably present the 401 error as logged in Blackboard's access log, not the 500 error as returned by LAMS.
