[Xerte-dev] Re: LTI Provider

[Ron Mitchell]

Hi Simon

thought I'd have a go at testing this for you but may be misunderstanding
how it works. Firstly will it only work with XOT configured for LDAP or
should it also work if XOT is set to static authentication?

 

Results of tests so far:

 

1. Realised I had to run upgrade.php to create the lti table - this worked
fine.

2. Adding a key and secret via management.php also worked fine.

3. Configuring the Moodle external tool via admin > manage plugins etc also
worked fine 

4. Adding an external tool activity to a course and selecting save and
display simply launches the XOT login page and upon login shows the
workspace e.g. there isn't an option to select a specific LO for the link.
Is this because it won't work with static authentication or am I missing
something?

 

HTH

Subject: [Xerte-dev] LTI Provider

 

First thank you all for the welcome.

 

Yesterday I submitted to svn the LTI Provider integration function I have
been working on.  This allow you to have launch Xerte from within a VLE
giving single sign on etc (In moodle this is the External Tool activity
plugin).  

 

It handles the association between the LTI userid & the Xerte username (and
allows regular re-authentication) and then if staff lets you select the
project you want to associate the link with, and then displays the project
for subsequent launches of the link.  It also includes LTI Key/Secret
Management in the main Xerte management interface.

 

I have tested it myself on my local box with a fresh install of Xerte
(configured for LDAP authentication) and Moodle 2.2.2+.  I have tried to
keep the changes as few as possible to integrate it in (I have extended a
couple of functions to support extra parameters as well as factoring some
repeated lines into functions so there is only 1 copy doing anything).  It
would be really useful if others could download it,  test it out and give
feedback.  

 

There is a very brief documentation file LTI Documentation.txt included with
a brief note of what you need to do, anyone having problems/or trouble
understanding how to get it working please get it touch.

 

The LTI library is based off the IMS sample code for LTI in php and extended
by UoN and has been used in the Rogo OSS project.

 

Thanks

 

Simon
