So after you've connected to the university network; maybe you need to use Desktop Anywhere and you've already installed your linux citrix client - but you're getting a complaint that it's not trusted?
At the time of writing Northumbria University use GlobalSign; their certificates are here:
http://www.globalsign.com/support/inter ... stall.html
But if you don't want to mess about (and I'm not sure which exact certificate it is, so you can just download all) you can run
'wget http://www.stanto.com/CA1.crt'
'wget http://www.stanto.com/CA2.crt'
'wget http://www.stanto.com/CA3.crt'
Or just download them yourself using the urls above.
They need to be put in the cacerts folder.
By default it's in:
/usr/lib/ICAClient/keystore/cacerts
You may need to 'sudo' the copying across or login as root again.
Enjoy.
