AEM form SSO error



Hi all,

We did AEM forms setup in our environment recently ( AEM 6.2 SP1).

We configured a form for one of our SSO (SAML 2.0) enabled website and when we submit the form, we are getting below error. Also the user ID with which we are doing SSO as access to :slider-mh" node and permissions are good.

"403 Forbidden"

"You don't have permission to access /content/forms/af/xyzsite/slider-mh/jcr:content/guideContainer.af.internalsubmit.jsp

on this server"

For Non-SSO site, this form is working as expected without any error.

So do we have do make any additional configurations on AEM forms to work on SSO enabled sites?
