I changed the server_id from a numbers to letters and shortened the server_key to a word (identical on both moodle and lams!!!) now I get a 500 error:

HTTP Status 500 -

type Exception report

Have you checked your Apache error log (if that's what you used for Moodle)?

I've found that in the Moodle release you may need to include Moodle's config.php manually in the lams module's lib.php. i.e., at the top of moodle/mod/lams/lib.php, put the line
require_once('/path/to/moodle/config.php');

> Also, I hope this isn't a dumb question but what is the server_id and how is it defined/created? is it simply a user created id similar to a user name???

That's pretty much it. server_key is the password.

Thanks for the quick reply. I added the line to the lib.php file and again checked that everything matched properly.

I now get this error appearing in a pink box on the lams module screen as the module is started:

An unexpected error returned from LAMS server:soapenv:Server.userException: java.rmi.RemoteException: Fail to fetch user data from external server:eee - Unexpected return HTTP Status; nested exception is: java.lang.Exception: Fail to fetch user data from external server:eee - Unexpected return HTTP Status! Please contact your administrator.

The last line of the apache error.log file says "[time] [error] [url] File does not exist: /var/www/mod"

Thanks for your help

Thanks for your assistance with my dramas...

Ah that makes sense, it was in the callback url! Glad to hear you got it worked out.

I'm guessing Moodle is installed in /var/www... but not sure why this error comes up? Is it possible you've made a syntax error in one of the php files?
