Hi Shankar,
This depends upon the first website that is accessed.
As SiteMinder module is defined globally.
The user used to start the LLAWP process depends on the application pool defined on the website/virtual directory that you are first accessing.
It does not matter even if the website is not protected with SiteMinder.
However, we have now fixed this in the newish version , such that now the LLAWP will start under the context of the application pool users of the first SiteMinder protected website which is accessed.
Regards,
Ujwol Shrestha
