Overview

The ValueRegex (basic:AttributeValueRegex prior to V3.2) type matches attributes values against the supplied Java Regular Expression.

Confusingly, theValueRegex type can be a Matcher or a PolicyRequirement.

  • If no attributeID attribute is specified then it is a Matcher (returning that value if it is present amongst the values, and the empty set otherwise)
  • If an attributeID attribute is specified then it is a PolicyRule (returning true if that value is present amongst the values for the specified attribute).

Schema Name

The ValueRegex type is defined in the urn:mace:shibboleth:2.0:afp namespace, which can be located at http://shibboleth.net/schema/idp/shibboleth-afp.xsd

Prior to V3.2, the deprecated basic:AttributeValueRegex type was defined in the urn:mace:shibboleth:shibboleth:2.0:afp:basic namespace, the schema for which can be found at http://shibboleth.net/schema/idp/shibboleth-afp-mf-basic.xsd

Attributes

Simple Profile Policy
<PolicyRequirementRule xsi:type="ValueRegex" regex="^hn.*$" attributeID="uid"/>

Simple Matcher
<AttributeRule attributeID="uid">
   <PermitValueRule xsi:type="ValueRegex" regex="^hn.*$" />
</AttributeRule>

Add any values of the attribute "uid" with start "hn" to its permitted values list.

Compound PolicyRule (deprecated)
<PolicyRequirementRule xsi:type="ValueRegex" regex="^hn.*$"/>

Apply this rule if any attribute contains a value which starts with hn

Compound Matcher (deprecated)
<AttributeRule attributeID="email">
   <PermitValueRule xsi:type="ValueRegex" regex="^hn.*$" attributeID="uid"/>
