Yep - I assume in the screen to add a LAMS activity, the dropdown menu for workspaces and sequences don't load? In the LAMS database table tbl_user does the Blackboard user exist with a prefix? (prefix set in ext_server_org_map). e.g. bb_administrator

Check your ext_server_org_map entry in the LAMS database (particularly the serverid/key and userinfo_url entries). Have a look at the access logs for LAMS and Blackboard (in LAMS, they are in C:\lams\jboss\server\default\log\localhost_access2006*.log. In the LAMS log we want to make sure that a request has been made to create a new user, and request the list of sequences, etc. Something like this:

137.111.246.8 - - [19/Oct/2005:13:11:29 10000] "POST /lams/services/LearningDesignService HTTP/1.0" 200 2736

(here a Blackboard user would see the dropdown menus 'loading' the list of workspaces/sequences)

192.168.111.56 - - [19/Oct/2005:13:11:40 10000] "GET /lams/LoginRequest?uid=instructor01&method=author&ts=1129691463791&sid=horizon-sakai&hash=be1588129d0f32ab13bc10a2edff0dba64d7e261 HTTP/1.1" 302 -
192.168.111.56 - - [19/Oct/2005:13:11:40 10000] "GET /lams/j_security_check?j_username=hs_instructor01&j_password=997fbbce1d0ef10d82f3a6fafcf41841 HTTP/1.1" 302 -

(since it is their first time, LAMS will create a new user on the fly)

192.168.111.56 - hs_instructor01 [19/Oct/2005:13:11:40 10000] "GET /lams/index.jsp HTTP/1.1" 200 10672

In the Blackboard access log, you want to see that the call for Blackboard user data has been made (sorry this isn't a real life example):

/webapps/lams-plglamscontent-bb_bb60/UserData?uid=%username%&ts=%timestamp%&hash=%hash%
