Variable regex transformation
Together with the mutual authentication behavior, this behavior affects how clients can authenticate themselves to edge servers and how groups within namespaces are authorized to access topics. It transforms a source string of the value extracted from the client certificate and stored as a variable, either client Id or Authorized Group(s). It lets you define a result string based on a regular expression search pattern.
- In the Property Configuration Settings section, click Add Behavior.
