Hi folks, 

I'm trying to configure a LTI interaction between mahara (19.04) and a Moodle.

On the LTI external apps configuration, the form ask for the external apps url... Unfortunately, the fields "apps URL" and "callback URI" are both disabled and I can't fill it.

To you have an idea why and how to turn arround ?

Many thanks in advance for your help.

Hi Lilian,

You do not need to worry about these two fields. I'll add a ToDo item to add some info to it into the Mahara manual. Since I do not mention them in the manual, they don't require any action. :-)

Best

Hi Kristina,

Many thanks for your answer. It's good to read you ;-).

Actually, the activity in moodle is not properly working : I've got a token error message (cf.screeshot bellow).

Everything seems to be well configured, so I thought it was because of this fields.

Do you have an idea of where it comes from ?

• The error :  

• The Mahara config : 
• The moodle config : 

My best regards,

Hi Lilian,

Sorry, I can't see from the screenshots what might have gone wrong. Do you use the default LTI setup or do you have some customisations on your site? I'd need to look at all the settings in both Mahara and Moodle step by step to see if anything was missed.

Cheers

Hi Kristina, 

I'm using the default LTI configuration regarding external apps (cf. screeshot).

Users connect on Moodle and Mahara through the OIDC plugin (Auth0 2).

The OIDC connexion is set as parent of the external app in Mahara.

What kind of screenshot or access would you need to have in order to find the issue ?

My best regards,

Hi Lilian,

We haven't tested the OAuth2 plugin for Mahara (can you please point me to it?) and thus don't know if you can use it as parent for LTI. Can you remove that connection please and see if plain LTI works, i.e. people only have web services listed as auth method and not OAuth2? It might be best to delete your test account from Mahara once you've remove OAuth2 as parent auth from LTI and only then test it so that the auth method will be set correctly.

Cheers
