SAML: Populating the UserDetails object

[erlendfg]

I have successfully implemented the SAML extenstion to my project. But I cannot figure out how to populate my UserDetails object. I read the documentation Vladimir Schäfer wrote about this, but unfortunately I do not understand what to do.

In another project using LdapAuthenticationProvider, I created an LdapAuthoritiesPopulator which populated the UserDetails object. But how do I do this using the SAML extenstion?

I figured it out. I populated my UserDetails object inside the loadUserBySAML method I had to create when I implemented the SAMLUserDetailsService interface.

I also created a helper method for getting the attributes:

private String getAttributeByName(final String name, final SAMLCredential credential) {
        Attribute attribute = credential.getAttributeByName(name);
        String output = "";
        if (attribute != null) {
            List<XMLObject> attributes = attribute.getAttributeValues();
            if (attributes.size() > 0) {
                for (XMLObject object : attributes) {
                    XSString string = (XSString) object;
                    output += string.getValue() + ", ";
                }
                return output.substring(0, output.length() - 2);
            }
        }
        return output;
    }
