MQTT and Kerberos/SSO

[Michal Kuzak]

Hi All,

Does a MQTT Client support Kerberos keytab when using Java or SSO via Browser when using JS? 

We are using IBM MQ V9 and have the Telemetry component for MQTT installed. 

I was wondering if there is a way when using the client paho classes to supply the Credentials from a keytab or from the browser context.

Thanks for any response in advance.

MQTT only supports u/p as a default, so I'm assuming that the Kerberos credentials are mapped into those fields. If that is the case, then the answer is that yes, any MQTT client can do it, but the hard work will be left up to you. I've not come across native support in any JS clients. 

To give you a similar example, I use OAuth2 credentials from JS in a browser, and I need to first make a call to the OAuth2 server to refresh the token, and then I pass the bearer token as the password.
