Do you think I got wrong certificates?

Hello!

I got this task on my desk and of course it needs to be solved fast.

We got an application with webapp and a webservice. I use to be able to access them with IE and SoapUI and the correct certificates.

The application is running in a wls that is fronted by a apache.
The appache was secured with a ClearTrust RSA.

A colleague has upgraded the system from ClearTrust to AccessManager. The last thing I heard was that he was done with it. But now he is on vacation and I can not get in touch with him.

We store all our cert in a source control app. So I have make sure that I use the latest one we got.

I just guess that he needed to change the certificates during the upgrade.

How ever now when I try to acces either one of the webapp or the webservice I get a 500 or a 404. Strangely I do not get the same from time to time.

My question now is if this symptom indicates that my cert that I use is wrong, or does it indicate on something else?

Even though I know that my colleague is very careful, perhaps he just forgot to update our cert in our source control app.

What do you think?
