"At least one security token in the message could not be validated". I got this error message when I tried to connect to CRM online thru my DNN(DotnetNuke) web portal.
Basically I have bypassed my DNN database. Instead, I have used CRM online as my database and DNN just connects with CRM online through CRM service.
It worked very well however every a few days, I got "At least one security token in the message could not be validated" error message when DNN was trying to authenticate and connect to CRM online. Reset IIS is a quick an easy fix. However it is really annoying everytime you have to reset IIS manually.
Please help.
