The M.O.S.T Commons LTI Tool is currently incompatible with Safari. We recommend using the LTI with Chrome or Firefox while we work to fix this. We apologize for the inconvenience.
Content Selection
The LTI tool allows any educator to browse and embed media objects alongside other content within assignments, or select content which comprises entire modules, lessons, or units. All users are able to search content added toM.O.S.T. Commons Collections. Additionally, users can also browse or search content from Group Shared Folders and personal My Items libraries, if that content has been configured and made available.
Authentication and Account Provisioning
The tool provides automated authentication and new account provisioning, providing users with an "SSO like" experience. The LTI key/secret pair can also be configured to automatically add new users to anM.O.S.T. Commons Group.
LTI Tool Preview Images
Some basic preview images of the tool have been included below. More details about using the LTI tool are available in the "Using the LTI tool" section of this guide.

Safari SSO Issue
The Problem:
I am using Safari and I can’t seem to login to the LTI Tool no matter what I do! I’ve even tried changing my password via reset password from email, and it still doesn’t work.
The Solution:
Check your cookie settings, and make sure you are allowing third party cookies. If you are strict about your cookie settings, you may need to whitelist vivaopen.oercommons.org
Close out of the LTI Tool
Open the Homepage https://most.oercommons.org/ in a new tab
Launch the LTI tool again
The Reason
Safari does a lot to protect your privacy, and ensure third parties aren’t tracking you without your consent. Because of this, Safari won’t allow third parties to set cookie information, if it looks like you haven’t visited the site recently. This means we can’t set an SSO cookie if you’ve recently cleared your history, are using Safari for the first time, or are using Safari on a new device. Opening the M.O.S.T. Commons Homepage will fix this problem, because it indicates to Safari that M.O.S.T. Commons is a site you use intentionally.
