For BioMedIT projects, user access to LeoMed is revoked via the BioMedIT portal (https://portal.dcc.sib.swiss/). The Permissions Manager removes users from the portal project (see WI-004 BioMedIT Portal User Management and SOP-003 User Management SOP). This automatically triggers a ticket with the LeoMed support team (see Contacting LeoMed Support) which will remove access to the LeoMed tenant for the user and will inform the user and Permissions Manager.
For further information on portal user management, see the authoritative BioMedIT documentation
