Ticket-Validation-Error // Checksum-Error

[qaiserajaz]

Hi to all experts over here.

I am having very strange issue regarding login into our CMS system. Basically we have a CAS web based system where the clients login and work. Whenever anybody is trying to login with their credentials behind PfSense , it is giving this error " Ticket-Validation-Error // Checksum-Error ". Everything is fine and pretty good in Pfsense and I've have given all access and opened all the traffic to a specific employee who used to login in the CAS web bases system but still its giving me this error. I tried to access it without Pfsense ( from another internet connection ) and it seems fine there. Could anybody please tell me what is the problem and how do I resolve this issue ?

I am using these services in my Pfsense.

Version : 2.1.1-RELEASE

Services : snort, squid proxy

Note : I also tried to adding login URL in the whitelist of Squid and disable the snort to see whether its working or not. but unfortunately it didn't work in that manner as well.

Here are the screenshots
