I am having an issue with SP-initiated federation when SP using HTTP-POST as there HTTP-BINDING. I found this CA knowledge base document regarding to this issue.
Here is the link:
According to this KD prior to SiteMinder version 12.52, HTTP-POST will not work with SP-Initiated if they are using HTTP-POST as their HTTP-BINDING and it always be a HTTP-REDIRECT. But from the version of SiteMinder 12.52, CA introduced both HTTP-POST and HTTP-REDIRECT into mix.
My issue is our SP provider is using HTTP-POST as HTTP-BINDING and it is working on Mozilla FireFox and it is not working on Chrome and IE. If SP is using HTTP-REDIRECT as HTTP-BINDING it is working on all three browsers.From IDP side we are allowing both HTTP-REDIRECT and HTTP-POST. I just want to know if anybody is having a similar issue or is there any resolution for this?
