The Jackrabbit Parent Portal is a hyperlink to our own SSL application. We do not recommend nor support embedding the Portal Login directly onto your webpage (via iframe or another method) because it then becomes subject to browser security restrictions.
Our Parent Portal Login is under SSL, and most browsers do not share sessions or cookies across domains and do not like mixing SSL and non-SSL pages. Having the Portal login embedded into your webpage can cause customer "session time out" errors (and other errors).
As well, Jackrabbit does not support SAML.
