RWTH Single Sign-On login ist not possible at the moment.
Existing sessions are not affected.
We are working on fixing the problem.

The problem has been solved.

Searching the library catalogue KatalogPlus, accessing the backend ALMA system as well as accessing the library user account in the RWTHApp will not be possible from Saturday, 12.07.2025 7:00h onwards. The provider moves the application. Resulting restrictions and limitations will be document at the UB website. The migration is scheduled for a maximal duration of 24h, this page here will be updated accordingly.

Minor delays have occurred. While the systems are already available, we are awaiting confirmation.

Migration completed. KatalogPlus and ALMA library system are operational. As planned registering for library use only possible from Monday morning onwards.

There are currently disruptions to RWTH Single Sign-On. After entering your login details, the screen loads and then an Internal Server Error appears. This affects all services that use the RWTH Single Sign-On login.
The specialist department has been informed and is working to resolve the issue.

The problem has been fixed.

In der angegebenen Zeit findet ein Update unseres MFA-Backends statt. Während dieser Zeit können neue RWTH Single Sign-On Sitzungen mit MFA nicht gestartet werden. Weiterhin sind neue VPN-Sessions nicht möglich. Bestehende Sitzungen (SSO & VPN) bleiben unbeeinträchtigt aktiv.
Aufgrund von fehlenden Policies konnten nicht alle Token gefunden werden und es kam zu Problem bei der Anmeldung.

Bitte beachten Sie, dass der RWTH Single Sign-On (SSO) während der oben genannten Zeit aufgrund geplanter Wartungsarbeiten für wenige Sekunden nicht verfügbar sein wird.
Betroffene Dienste: Alle Anwendungen, die den SSO verwenden.
Auswirkungen: Es können keine neuen Sitzungen gestartet werden und bestehende Sitzungen sind nicht nutzbar. Nutzerinnen und Nutzer in bereits geöffneten Anwendungen können jedoch bis zu ihrem Logout normal weiterarbeiten.
Während der Wartung sehen Sie eine entsprechende Wartungsseite.

This evening around 20:25 - 21:00 there was a performance low in the SSO service and was checked by the specialist department during this time. The problem has been solved and fast logins without waiting times are possible again.

At the moment, single sign-on and multi-factor authentication are sporadically disrupted. We are already working on a solution and ask for your patience.

For a short period of time, there was an error while using RWTH Single Sign-On.
The problem has been solved.

Due to the expired certificate for idm.rwth-aachen.de, no IdM applications and the applications that use RWTH Single Sign-On can be accessed.
We are working on a solution.
- An insecure connection message is displayed when calling up IdM applications.
- When calling up applications with access via RWTH Single Sign-On, a message about missing authorisations is displayed.

The certificate has been updated and the applications can be accessed again. Please delete the browser cache before accessing the pages again.

Aufgrund von Erneuerung der SSL Zertifikate wird der vCenter Server im genannten Zeitraum teilweise kurzzeitig nicht erreichbar sein.
Alle VMs laufen wie gewohnt weiter und die Erreichbarkeit der darauf laufenden Dienste wird NICHT durch diese Wartung beeinträchtigt werden. Lediglich die Funktionen des HTML5 Clients für das Management ihrer VMs werden nicht verfügbar sein, da Sie sich während der Wartung nicht am vCenter Server einloggen können.

Während der Wartung ist es zu Fehlern gekommen, sodass die Wartung verlängert werden muss.

Due to maintenance, some servers are currently unavailable.
There are temporary connection problems with some services.

Since July 2, 2024, the RWTH Single Sign-On (SSO) and the login of all SSO-connected services is protected with multifactor-authentication (MFA). In addition to an individual password, users must now enter a second factor when logging in. The second factor must be generated in Selfservice [1] via the Token Manager. Further information can be found on IT Center Help [2] and the IT Center Blog [3].

Unfortunately, the login via the RWTH Single Sign-On and thus into the connected services is currently only successful in individual cases.
If you receive an error message, please try to log in again in about an hour.
People who are already successfully logged in are not affected by the disruption.

The servers are currently at full capacity. We therefore ask you to try to log in at a later time (approx. in one hour). We are working on a solution to the problem.

Through various measures, which have significantly increased the overall performance of the servers, the loading difficulties and login problems were resolved around 3 pm.
For the time being, the message remains as a note, as we continue to monitor the load on the system.

The login to the RWTH Single Sign-On is stabilized. For this reason, we are ending this notice.

For the installation of Updates, the creation of library accounts via Self Service is temporarily unavailable.
