In 2020, the University of Texas System announced the consolidation of UT Tyler with the UT Health Science Center Tyler into a single institution that included the merging of the campus identity system and moving away from a self-hosted EZ Proxy instance. Despite the unified vision to "Rise as One," we maintained two distinct libraries to serve the academic and health campuses of the newly combined UT Tyler. This decision presented challenges in user authentication and access management. In this session, we will discuss how we implemented and continue to manage OpenAthens to address these challenges, ensuring seamless and secure access to library resources to our diverse user populations.
