Identity Attribute Rule

Overview

This rule calculates and returns an identity attribute for a specific identity. This rule is known as a "complex" rule on the identity profile.

An important consideration with IdentityAttribute rules is whether generation logic that includes uniqueness checks is acceptable. While not explicitly disallowed, this type of logic is firmly against SailPoint's best practices. When calculating and promoting identity attributes via a transform or a rule, the logic contained within the attribute is always re-run and new values might end up being generated where such behavior is not desired. Additionally, the attribute calculation process is multi-threaded, so the uniqueness logic contained on a single attribute is not always guaranteed to be accurate. For this reason, SailPoint strongly discourages the use of logic that conducts uniqueness checks within an IdentityAttribute rule. The recommendation is to execute this check during account generation for the target system where the value is needed.

Execution

• Cloud Execution - This rule executes in the Identity Security Cloud cloud, and it has read-only access to Identity Security Cloud data models, but it does not have access to on-premise sources or connectors.
• Logging - Logging statements are currently only visible to SailPoint personnel.
• Usage - To use this rule once installed, first select "Complex Data Source" option under the Source dropdown, then select the rule name under the Transform drop down.

Input

Argument	Type	Purpose
log	org.apache.log4j.Logger	Logger to log statements. Note: This executes in the cloud, and logging is currently not exposed to anyone other than SailPoint.
idn	sailpoint.server.IdnRuleUtil	Provides a read-only starting point for using the SailPoint API. From this passed reference, the rule can interrogate the Identity Security Cloud data model including identities or account information via helper methods as described in IdnRuleUtil.
identity	sailpoint.object.Identity	Reference to identity object representing the identity being calculated.
oldValue	java.lang.Object	Attribute value for the identity attribute before the rule runs.

Output

Argument	Type	Purpose
attributeValue	java.lang.Object	Value returned for the identity attribute.

Example - Calculate Lifecycle State Based on Start and End Dates

info

The life cycle state attribute is computed last during refresh. This allows you to reference other identity attributes within the rule.
