The Internet of Things: Edge Connect product allows connected users and devices to communicate on a publish-subscribe basis within reserved namespaces. In conjunction with dcpAuthVariableExtractor, this behavior affects how clients can authenticate themselves to edge servers, and which groups within namespaces are authorized to access topics. It transforms a source string value extracted from the client certificate and stored as a variable, then transforms the string based on a regular expression search pattern, for use in authenticating the client request.

Note that you can apply this regular expression transformation, or either of the dcpAuthHMACTransformation or dcpAuthSubstringTransformation behaviors.

Option Type Description Requires

Option	Type	Description	Requires
`regexPattern`	string	Specifies a Perl-compatible regular expression with a single grouping to capture the text. For example, a value of `^.(.{0,10})` omits the first character, but then captures up to 10 characters after that. If the regular expression does not capture a substring, authentication may fail.		{"displayType":"string","tag":"input","type":"text"}
