Apply for Access to Collections with Access Restrictions
When viewing an item that has restricted access, you will see one of the following permission warnings, depending on whether or not you are logged in to the portal:
- You do not have permission to see these files. Sign up or Login
- You do not have permission to see these files. You are logged in and you can apply for permission to view these files apply for access or refresh permissions

The LDaCA environment uses CADRE for access control. Once you have logged in to the LDaCA portal (see Login for further details), select apply for access in the warning text and you will be directed to the CADRE login page in a new tab.

Select Login and follow the CILogon prompts (see Login again). Once logged in, you will be able to complete the data license form and request access. Data licensing is the mechanism used in CADRE for data stewards to grant or deny legal permission to access and use data. Follow this guide for applicants to learn more about navigating CADRE.
Once the data sharing request is approved, navigate back to the data object you require in the LDaCA portal. If the warning text is still displayed, click on refresh permissions. The page will update and you should be able to access the data. Note that these permissions apply to other data objects in the collection that are covered by the same license terms; you do not need to apply for permission for each data object.
