Authentication proxy problem

[LLSJ Krüger]

Hi,

I don't know if this is the right forum to ask, if not please tell me
where I should.

I worked for the University of Pretoria (UP) and my authentication
always first went to their page and I could then access the indexed
material.

I no longer work for them, but should have access through another
university.

At this stage if I try to access material I still get redirected to UP.

How can one fix this?

Regards,

Louis.
