OpenAthens is a hosted identity and access management service that provides a streamlined solution for implementing single sign-on authentication. This presentation will outline the steps East Tennessee State University took to configure OpenAthens authentication across the Alma, Primo, and EZproxy platforms. We will give a brief overview of the internal configurations related to LDAP integration, allocating electronic resources, and selectively assigning permissions. Finally, we will share our experiences with OpenAthens including support, vendor adoption, and end user benefits.
