UsingWW: First student login with 2.19 sometimes fails to create an account?

You will want $CookieSecure = 1;. There is really no case where that should be 0 anymore. We need to change the default for that.

There are no real changes to LTI 1.1 authentication from WeBWorK 2.18 to 2.19. Content item selection was added, but that doesn't change the way that authentication works. So there is probably something in the configuration of the 2.19 server that is not set up right.

You noted that you have $authen{user_module} set in both authen_LTI.conf and in localOverrides.conf. It sounds like you want the one in localOverrides.conf to be in effect. That means that the one in localOverrides needs to be after the authen_LTI.conf file is included in localOverrides.conf. So make sure that is how it is set up.

Another thing to try is to enable the debugging facilities. There are two of them that apply in this case. The first is $debug_lti_parameters in authen_LTI.conf. The second is much more general and comprehensive. That is to set


debug:
  enabled: 1

in the webwork2.mojolicous.yml file. If you do that you will also want to set the "logfile" option below that or you won't see the debugging messages anywhere when running webwork2 with hypnotoad.

Thanks Glenn,

=========== summary ============
User id is |jpeismeier| (obtained from lis_person_contact_email_primary which was preferred_source_of_username)
User mail address is |jpeismeier@wpi.edu|
strip_domain_from_email is |1|
Student id is |jpeismeier|
preferred_source_of_username is |lis_person_contact_email_primary|
fallback_source_of_username is |lis_person_sourcedid|
preferred_source_of_student_id is |custom_canvas_user_login_id|

is the summary of setting debug_lti_parameters to 1 which seems okay for my simple test. The debug set in webwork2.mojolicous.yml was already there? It will take a while comparing students that were blocked vs students that LTI created accounts for.

When comparing 2.18 to 2.19 I did find this last weekend the lms url had a typo in both instances. Repairing 2.19 didn't alter the intermittent account creation concern that I see.

If you mean the $LTI{v1p1}{LMS_url}, that won't matter. That isn't used for authentication. That is only used to display links in WeBWorK to the LMS when authentication fails or on logout.

If you have debug in webwork2.mojolicious.yml set, then try to compare the output in the debug.log file between a user for which LTI authentication works correctly and a user for which is fails, and report differences here. It can be a bit challenging to sort out, because there is a lot of output generated. You might want to watch that log file for size too. It can become quite large rather quickly when debug is enabled on a production server.

Does this help explain our issue? This is a course where most students have homework access with LTI creating their account first login.

This student appears to have success from the same course.

Re: First student login with 2.19 sometimes fails to create an account?

by Glenn Rice - Thursday, 23 January 2025, 11:31 AM

In neither of those cases is LTI authentication being used. In both cases it starts with

WeBWorK::Authen::LTIAdvanced::request_has_data_for_this_verification_module: LTIAdvanced returning that it has insufficent data

That means that in both cases it is moving on to the LDAP authentication module and authentication occurs with that module.

Re: First student login with 2.19 sometimes fails to create an account?

by Alex Jordan - Thursday, 23 January 2025, 2:38 PM

"LTIAdvanced returning that it has insufficent data" is returned if one of oauth_consumer_key, oauth_signature, oauth_nonce, or oauth_timestamp is not defined in the params for the LTI request. If you edit line 112 of lib/WeBWorK/Authen/LTIAdvanced.pm, you could have the log also print the values of these params to track down which one(s) are missing, to narrow the issue down.

I missed which LMS you are using, but in D2L, when I am an instructor, I can visit the External Learning Tools manager and click to view the link request, where I can see the params it would send. Maybe other LMSs let you do something similar. Of course, this may not help if it is sending them for you but not for one of your students.

Re: First student login with 2.19 sometimes fails to create an account?

by John Eismeier - Thursday, 23 January 2025, 3:36 PM

I am using canvas. With LTI debug turned on this morning I do see:

oauth_nonce => sM4aluonWpqDLfUeD4tA4UcdO7X5CkKB0RgXPIY2Y
oauth_signature => fLy6aiBZfbIMBt8pF72WwsIQa/w=
oauth_consumer_key => Webwork
oauth_timestamp => 1737628800

so is there issues LMS side sending oath some times or configuration webwork side that I missed or didn't define correctly? I will try to print from the perl module using the debug call to print ?

by Danny Glin - Thursday, 23 January 2025, 6:40 PM

Other than the extra w at the end of "nonce" that looks like it should work.

From what you've posted so far there still isn't an instance showing that a student successfully logged in via LTI. In the course login log look for entries that include "credential_source=LTIAdvanced". If you can find an entry with a user_id that belongs to a student then we can try to determine what's different about that student.

Re: First student login with 2.19 sometimes fails to create an account?

by Glenn Rice - Friday, 24 January 2025, 6:40 AM

Anytime that you see

WeBWorK::Authen::LTIAdvanced::request_has_data_for_this_verification_module: LTIAdvanced returning that it has insufficent data

in the debug log that means that one of the one of the oauth parameters (oauth_consumer_key, oauth_signature, oauth_nonce, or oauth_timestamp) was missing. If any of those parameters are missing, it most likely is not a configuration issue at all that is causing the issue. Are you sure that the instructor that created these links in Canvas actually used an "External Tool" setup for the links? If the instructor created an "External URL" link as a Canvas module, then it will not work for LTI authentication. Some instructor using a basic link instead of an external tool seems more likely to be the root of these issues than anything else.

Note that there is no reason to add debugging statements to the code to see this if you have debug in webwork2.mojolicious.conf turned on. All parameters received in the request are shown in the debug log already.

If you have debug_lti_parameters turned on and are not getting the message "Nonce Expired. Your NonceLifeTime may be too short", then tuning NonceLifeTime is probably not going to help.

I have not verified all class work but for calc 1 I have attached the canvas side. Does this seem wrong?

The student I mentioned in today's post has both LTI success and failure within a close time period. I was not at this students screen when LTI was turned on but this does suggest to me increasing NonceLifeTime to maybe 120 vs current 60

While canvas is cloud based, with webwork is on campus in our datacenter.

That looks right for the Canvas external tool setup. You can try changing the NonceLifeTime and see if it helps. I doubt that it will, but it is worth a shot.

Re: First student login with 2.19 sometimes fails to create an account?

by John Eismeier - Friday, 24 January 2025, 8:04 AM

Thank you Glenn. Still seems like LTI is not fully functional. Why does grade pass back work well in both 2.18 and 2.19. From what I have learned in this thread, I am not sure LTI auth has ever fully worked correctly for WPI.

Our brief history included 2.13 not able to use grade passback. I deployed the 2.15 VM from the MAA site which worked well. With 2.15, our webwork performance improved and grade pass back worked.

Seems like I need to still focus on the oauth parameters (oauth_consumer_key, oauth_signature, oauth_nonce, or oauth_timestamp) that are missing ?

Re: First student login with 2.19 sometimes fails to create an account?

by Glenn Rice - Friday, 24 January 2025, 8:50 AM

It sounds like something is intercepting the request from Canvas to WeBWorK and not forwarding it properly. So by the time it reaches WeBWorK it is missing parameters. Is there a proxy of some sort involved here?

Re: First student login with 2.19 sometimes fails to create an account?

by John Eismeier - Friday, 24 January 2025, 10:26 AM

The only proxy that I am aware of is the reverse proxy to webwork2 service on the webwork server.

Does the webwork server with apache need any special configs outside of the like Header always set X-Permitted-Cross-Domain-Policies ?

Re: First student login with 2.19 sometimes fails to create an account?

If you are using the conf/webwork2.apache2.4.conf file, then everything that is needed should be set. If you aren't using that file, then you should check it for things that are needed.
