Cust-R2 Authentication Failures

Created: 12 May 2014 • Updated: 05 Jun 2014

I've been trying to resolve an issue of multiple Cust-R2 authentication failures occuring on our network. The authentication failures appear to be occuring when the user tries to authenticate to our web proxy. The failures do not register as network authentication failures. I did see a different, older post regarding Cust-r2 and LUA, but can't seem to find any correlation between the two in this scenario. We are using SEP 12.1.

Any help or suggestions would be appreciated. Below are some of the details from our logs.
