Hello-
We have over 200 users using our reports and every day 20-30 people reporting authentication issues intermittently. They are able to access it again on re-trying after some time or clearing cache but this happens at least twice or thrice a week to most of the users and it doesn't seem normal.

Any idea what could be the issue?

First question here would be what authentication are you using, a SSO from front end or logging in the BI portal? And is there a load balancer / cluster involved?

"Clearing cache" solving the issue... a proxy cache set in IIS?

SSO from front end and yes there is load balancer and cluster invovled.

"I have a hunch", and it tickles some memory I've seen this before...

1. Ok, starting with the browser - IIS (or apache) and further on so you need to go through the pipeline and first check if there is any caching set, and set it off. Don't assume the F5 isn't caching - check everything...

2. Check the clustering configs that there isn't any hardcoded stuff pointing to the other cluster box... like when you clone the boxes and clone the configs... and clone the box names as well so stuff actually points to the first box you cloned from... been there, done that...

Hi Kartik

I think you need to open a case with techsupport. They can help you with traces etc to hopefully find out where things are going wrong.

Regards,

I was raising a new discussion when I bumped in to this one when i realized i didn't respond to this. So here's what we found:

Since our application was using Global variables(&&) which were being set with a .fex profile inside an "iframe", the intermittent issue was because of the timing.
Javascript code was not waiting for the iframe to load completely because at times it was too slow due to any reason. Just introduced a timeout to give those extra seconds for the frame to load which did the trick.
