Art O Cathain created SHIRO-442:
-----------------------------------
Summary: CAS client fails with multi-valued SAML attributes
Key: SHIRO-442
URL: https://issues.apache.org/jira/browse/SHIRO-442
Project: Shiro
Issue Type: Bug
Components: Authorization (access control)
Affects Versions: 1.2.1
Reporter: Art O Cathain
Fix For: 1.2.3
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
