Case sensitivity on Alternative Hosts field - is it possible to make case insesntive

[simon-kanz]

Hi All,

Thanks for this plugin, we've used it to great success however have noticed that we have an issue where some of our users have capital letters in their email addresses.

Scenario -
User email address: Jo.Blogs@invalid.com
Email address matches in Zoom and Moodle using the specific format above.

Our LMS team adds Jo as an alternative host on a call using the email address "jo.blogs@invalid.com"
When Jo tries to access the meeting, they will get the blue "Join Meeting" button and be unable to start the call.
If Jo attempts to start the meeting they'll then get an error on the Zoom side saying "You have a meeting that is currently in-progress. Please end it to start a new meeting"

Our LMS team then updates the alternative host to use the correct format "Jo.Blogs@invalid.com" as an alternative host.
When Jo tries to access the meeting, they will get the green "Start Meeting" button and can start the call successfully.

For the moment we've asked the LMS team to ensure that they use the correct format for the users, however, they are not always aware of what the exact format should be. Is it possible to make this lookup case insensitive? I'm not sure if this is a problem on Zoom's side or the plugin itself

Hi @simon-kanz,

This does seem like a bug that we can address in the plugin. I hope that Zoom is already doing a case-insensitive lookup when we request information for a user's account. I think we were assuming that the email addresses would always match and PHP string comparisons are, in general, case-sensitive. So what we should probably do (in the plugin) is programmatically lowercase all email addresses so that PHP's case-sensitive string comparisons do not get confused.

Hi @jrchamp
I've got an open support request with Zoom to find out if their service is case-sensitive. If you were to update to use case-insenstive lookups, it's likely that it would break the lookup for any user who has mixed cases in their email!

Hopefully Zoom get back to us soon and advise that email is case-insenstive and your recommendation would be solve the issue.

Hi @jrchamp
Zoom support have responded to us, saying that their username and email fields are not case-sensitive.
That likely means that you could update the logic to lowercase all email addresses

Thanks @simon-kanz! That's great to know. We'll add this to our worklog and prioritize it appropriately.
