If you would like to connect web services to the TU Darmstadt Single Sign-On (SSO) federation, please contact us, as we need to activate each individual service. Important condition: The service must be provided under a TU Darmstadt subdomain – *.tu-darmstadt.de. Domains outside this namespace cannot be connected.
The connected service can use the attributes provided to decide for itself which persons it wishes to allow.
