The LDAP address book (LDAP = Lightweight Directory Access Protocol) is a type of database or directory that an email application queries via a predefined path (server name, port, branch/search base) in order to find out the user certificate of an email address, for example. If such an LDAP address book is integrated into your own email application, encrypted emails can be sent directly, for example, provided the recipients have published their user certificate in the LDAP address book. Not every e-mail has to be sent encrypted, but you can select this option if you wish and after successful setup. Read more about the encryption of emails in part 2 of the blog series.

It regularly happens that personal data or other sensitive information such as temporary passwords, application documents etc. need to be transmitted quickly. The choice often falls on the exchange by e-mail. However, this data must be protected against unauthorized access by third parties. In order to still be able to use e-mail, the e-mails must be encrypted. We will show you how this works in the following blog post, along with other relevant information on the subject. Go back to the first blog post in our series to read more about digital signatures.

Did you know that in June 2024, more than 80% of all incoming emails at RWTH Aachen University were identified as suspicious by the email security defense systems? [1] You may now be thinking of terms such as phishing emails or spam emails.
At some point, every recipient of an email asks themselves the question: How do I know whether the sender address is trustworthy and genuine? On the other hand, every sender asks themselves at some point: How do I know whether my email has demonstrably reached the recipient unchanged? One answer to this is: Always sign emails digitally! We would like to take a closer look at this process with you in the following blog post.

On May 3, 2023, the login process for our GitLab instances (git.rwth-aachen.de and git-ce.rwth-aachen.de) will be updated as part of a necessary maintenance.
However, in order to be able to log in to the GitLab instances of the RWTH after the maintenance, the primary e-mail address stored in GitLab must match the contact e-mail address in the Identity Management of the RWTH. Otherwise, if the e-mail addresses are different, you may get a login error after the system changeover.
