How to unblock blocked webportal user?

#1

Hi,
I just was confronted with the situation that a user did enter the password wrong too often and afterwards even the valid credentials did not allow to login anymore. Since other users still were able to login, I assume there is a feature which is preventing trying that too often. I would like to find out if that is done by the KNIME server and how to adjust the settings belonging to that and how to reactivate a user account manually. If all of that is not done by the KNIME Server it could be a feature of our nginx.

THX,
Lars

Hi Lars,

That’s handled by the LockOutRealm feature of TomEE.
http://tomcat.apache.org/tomcat-8.5-doc/realm-howto.html#LockOutRealm

With default settings the user should be able to login again after 5 minutes:

Hi Jon,

thanks a lot for the quick answer. I checked the links and what I have in our server file is

which means it is not defined (default used) I assume. As I also found, the standard settings should be 5 Minutes then, as you mentioned, but the user is blocked since several hours now.

Is there beside of this option a way to simply unblock a desired user?

Thank you!
Lars

Hi Lars,

A KNIME Server restart will also reset the lockout realm and allow the user to login.

Best,
