> When using org.apache.shiro.cas.CasRealm, if the SAML returned by CAS contains multiple attributes of the same name (e.g. roles?), CasRealm blows up in doGetAuthorizationInfo
> String value = attributes.get(attributeName);
>  with
> java.lang.ClassCastException: java.util.ArrayList cannot be cast to java.lang.String
> This is because the org.jasig.cas.client.validation.Saml11TicketValidator is populating the attributes in the
> principal as follows:
> personAttributes.put(samlAttribute.getName(), values.size() == 1 ? values.get(0) : values);
> See attached patch for a fix
