  • Issuer. The SAML issuer specified in the assertion.

 

Parameter (con't)

  • AttributeXPath. A standard XPath query run against the SAML assertion. The query obtains the data that is substituted in a search specification that looks up a user-for example:

//saml:AttributeValue/SM:/SMContent
/SM:Smlogin/SM:Username.text()

This query gets the text of the Username element.

  • attribute. The search string for looking up a user in a user directory of the specified type. Use a percent sign ( % ) to indicate where the value returned from the XPath query should be inserted. For example, if you specify attribute LDAP:uid=%s, and user1 is returned from the query, the search string used for LDAP directories is uid=user1. At least one attribute must be specified.

Format of the parameter string is as follows. Separate name/value pairs with semi-colons ( ; ). The format example includes LDAP and ODBC attributes:

Name=name;SAMLProfile=POST;
SAMLVersion=1.1;RedirectMode=0|1|2;
AssertionConsumerURL=consumerUrl;
Audience=audience;Issuer=issuer;
AttributeXpath=XPathQuery;
attribute=LDAP:srchSpc;attribute=ODBC:srchSpc
