Léo UGA relies on the CAS (Central Authentication Service) protocol from Apereo, deployed by the DOSI of the University Grenoble Alpes. The authentication URL points to leo.univ-grenoble-alpes.fr/cas, and any attempt to access a federated service (Zimbra email, grade report, timetable) triggers a redirect to this unique landing page. Understanding this mechanism avoids most of the blockages encountered at the start of the academic year.
CAS Mechanism and Session Management on Léo UGA
The CAS server generates a session ticket (TGT) stored in a browser cookie. As long as this cookie remains valid, the student can navigate between UGA services without re-entering their credentials. However, closing the browser invalidates the TGT, which corresponds to the security guideline published by the university on the official authentication page.

We recommend never checking “stay connected” on a shared computer in the library or computer lab. UGA’s CAS treats Léo as a sensitive session service: logging out and completely closing the browser are explicitly requested by the institution.
A point often overlooked: browsers that automatically restore tabs on startup may retain an expired CAS cookie. The result is a redirect loop between the target service and the login page. The workaround is to clear the cookies for the domain univ-grenoble-alpes.fr, or to use a private browsing window. For useful information on Soutien Adom, the detailed procedure addresses this scenario.

UGA Credentials and Activation of the Agalan Account
The login identifier for Léo is the Agalan identifier, assigned during administrative registration. It takes the form firstname.lastname (sometimes followed by a number in case of duplicates). The initial password is set via the Copass platform, accessible from the “Forgot password?” link on the CAS landing page.
Activating the Agalan account is a prerequisite for accessing all digital services of UGA. Without this step, no CAS ticket can be issued, and the landing page simply displays an error regarding the credentials.
Reset via Copass
Copass (copass-client.grenet.fr) offers two distinct pathways: resetting a forgotten password and voluntary change. The reset requires the personal email address declared during registration. If this address is no longer accessible, the only recourse is the SOS Étudiants desk, physically located on campus (Michel Dubois building, among other locations).
- Check that the personal email address declared at registration is still active before the start of the academic year
- Keep the Agalan activation email received after administrative registration, as it contains the exact identifier
- Do not confuse the Agalan password with that of the Eduroam wifi, which may differ depending on the initial configuration
UGA Student Portal or Direct URL: Which Entry Point to Choose
Two paths lead to Léo. The first goes through the direct URL leo.univ-grenoble-alpes.fr, which immediately displays the CAS landing page. The second goes through the UGA student portal (etudiant.univ-grenoble-alpes.fr), which offers an explicit link “log in to the Léo student intranet” from the dedicated section.
The student portal remains the recommended institutional access point. It aggregates links to other services (CVEC, registrations, campus) and offers a broader navigation context than the raw landing page. For quick daily use, a bookmark to the direct URL is sufficient.
Be careful not to confuse the student portal with the Campus UGA application. The latter, notably highlighted by the STAPS component, serves campus life (maps, events, alerts) but does not provide access to Léo’s academic functionalities (grades, timetable, enrollment certificate).
Variability of Sections According to Components
The UGA component pages (LLASIC, STAPS, Medicine, IAE) all link to Léo, but the highlighted sections vary by UFR. A STAPS student will see the agenda and sports results prioritized, while a literature student will first access educational resources and messaging. This customization depends on the configuration applied by each component on the Léo portal.
Resolving Common Connection Errors on Léo
The majority of connection issues with Léo fall into three categories, and none require contacting the DOSI as a first step.
- CAS Redirect Loop: clear the cookies for the domain univ-grenoble-alpes.fr or switch to private browsing. The problem almost always comes from a corrupted or expired session cookie
- Error “incorrect credentials” even though the password is correct: check that the Caps Lock key is off (the CAS landing page displays a dedicated warning) and that the entered identifier is indeed in the format firstname.lastname, without the suffix @univ-grenoble-alpes.fr
- Blank page or timeout: peak loads at the start of the academic year saturate the CAS server. Wait a few minutes or try accessing outside of peak times (early morning, late afternoon)
If the problem persists after these checks, the SOS Étudiants desk remains the dedicated support channel. This service, documented by the UFR Arts and Humanities, addresses issues with credentials and access rights directly on-site.
UGA also provides an official video tutorial on its POD platform (videos.univ-grenoble-alpes.fr), which visually details the login process and the main functionalities of Léo. This multimodal support complements the textual documentation for students discovering the university’s digital environment.
Lastly, keep in mind: Léo also federates access for students enrolled in partner components (Grenoble INP, Sciences Po Grenoble, ENSAG). The Agalan identifier works the same way, but the services visible after login depend on the student’s administrative affiliation. Checking one’s profile in Léo after the first login ensures that the right resources are properly linked to their account.
