General

In this sample expression, the value of the attribute “net-worth” is transformed first to eliminate any dollar signs or commas, then the result is evaluated to determine whether the user's net worth falls into a “bronze,” “silver,” or “gold” category.

#result=#this.get("net-worth").toString(), 
#result=#result.replace("$",""),
#result=#result.replace(",",""), 
#result < 500000 ? "bronze" : 
#result < 1000000 ? "silver" : "gold"

Multivalued attribute

new org.sourceid.saml20.adapter.attribute.AttributeValue( {"Blue", "Gray", "Pink"})

This expression formulates a multivalued attribute in an SSO token.

<saml:Attribute Name="clrs" ...>
  <saml:AttributeValue ...>Blue</saml:AttributeValue>
  <saml:AttributeValue ...>Gray</saml:AttributeValue>
  <saml:AttributeValue ...>Pink</saml:AttributeValue>
</saml:Attribute>

and

{
  ...,
  "clrs": [
    "Blue",
    "Gray",
    "Pink"
  ],
  ...
}

In these truncated samples, clrs is the multivalued attribute. The former is a SAML assertion through a SAML service provider (SP) connection. The latter is a JSON web token (JWT) through a WS-Federation SP connection using JWT as the token type.

Token authorization

This expression verifies whether a user is a member of the “Engineering” or “Marketing” group.

#this.get("ds.memberOf")!=null?
(
  (
    #this.get("ds.memberOf").hasValue("CN=Eng,OU=E,DC=contoso,DC=com")
    &&
    #this.get("context.VirtualServerId").toString().equals("Engineering")
  )
  ||
  (
    #this.get("ds.memberOf").hasValue("CN=Mkt,OU=M,DC=contoso,DC=com")
    &&
    #this.get("context.VirtualServerId").toString().equals("Marketing")
  )
):false

The following expression extracts the domain information out of an email address (mail) and returns true if it matches a specific domain. 

#this.get("mail")!=null?
(
  #email=#this.get("mail").toString(),
  #atSign="@",
  #at=#mail.indexOf(#atSign),
  #at > 0?
    (
      #domain=#mail.subject(#at+1),
      #domain.matches("(?i)example.com")
    ):false
):false
Note:

Line breaks are inserted to both samples for readability only. You must enter statements calling methods whose arguments are enclosed in quote on a single line.

This sample expression returns true when the IP address of the client is within the specified CIDR range of fe80::74da:14b:76d1:eba3/128.

#isWithinCidrRange = @com.pingidentity.sdk.CIDROperations@isInRange(#this.get("context.ClientIp"),"fe80::74da:14b:76d1:eba3/128")

The isInRange method supports both IPv4 and IPv6 CIDR notations.

HTTP request context

You can use the following example to retrieve a value from an HTTP request object. The expression retrieves the User-Agent HTTP header value and compares it against a value required for token authorization.

#this.get("context.HttpRequest").getObjectValue().getHeader("User-Agent").equals("somevalue")

STS client authentication context

This security token service (STS) SSL Client Certificate Chain example checks that the issuer of the client certificate matches the specified distinguished name (DN).

#this.get("context.StsSSLClientCertChain").getObjectValue()[1].getSubjectX500Principal().equals(new javax.security.auth.x500.X500Principal("CN=Ping Identity Engineering,OU=Engineering,O=Ping Identity,L=Denver,ST=CO,C=USA"))
Note:

#this.get("context.StsSSLClientCertChain").getObjectValue() returns an array of java.security.cert.X509Certificate instances. This array starts with the client certificate itself.
