SSO/SAML on AEM Publisher
I am currently working on implementing an asset manager using Adobe AEM 5.6.1 DAM and want to use the Asset Share and Asset Editor templates on publisher. Our client however needs these pages to be secure and restrict access to users who authenticate through a SAML-based SSO product. The SAM authentication handler configuration on Author instances is pretty straight forward but when attempting to do the same on publisher it does not work. The default behavior when using Asset Share page on publisher is that it redirects to the geometrix login (not AEM) page. I understand that this can be changed to a different page but I need it to redirect to the IdP login screen. When I configue the SAML authentication handler on publisher with the same exact parameters that work on author I not only am not redirected to the IdP to enter credentials, but I am not prompted for any authentication at all.
Is there a setting or something that I am missing somewhere on a publisher instances to enable the SAML authentication handler the same way it works on an author instance?
Any help and advice would be greatly appreciated.
