In my second project involving IBM Tivoli Access Manger SSO I experienced a problem with Interactive Report sorting and utilization of different jQuery techniques. There is a nice description on how to set up APEX to work with IBM TAM SSO available here:

One more thing needs to be added to this document. Probably, your IBM Admin will set it up using junctions. As I said, this will cause problems with Ajax since IBM TAM will add a small javascript to the end of the HTTP response. Something like:
<script>
document.cookie = "IV_JCT=%2Fjunction_name";
</script>
and APEX will have problems with interpreting that response. Json, used for IR sorting will not work at all.
To work around this problem, you will need to talk to the administrators and let them set it up using mapping tables as described in this document:
