If I go to <https://sitecatalyst.omniture.com/login/>, and try logging in, my login to intranet works, but I get redirected back to an Omniture login page. Here's a video of it: <http://ilias.ca/flashback/omniturelogin.html>
You're not listed as a user on Omniture. Did you have access but now do not, or are you requesting access?
Actually, after double-checking, you are listed but it's not under your current LDAP account. I think this has something to do with your LDAP accounts being merged recently IIRC. I'll fix your account now.
Should all work now.
