If the PwdLastSet attribute in Microsoft Active Directory (AD) is null, RSA Identity Governance & Lifecycle's AD Account Data Collector (ADC) incorrectly collects the value as the date 9999-12-31 with a time value that represents the time of the last collection.
For example, the PwdLastSet attribute may be collected as 9999-12-31 12:45:50. Since the time portion of the attribute may change between subsequent collections, this may incorrectly cause the Account to be marked as Changed even though there was no change to the collected values.
The date calculation for PwdLastSet is being done incorrectly. Other date attributes should not exhibit this issue.
This is a known issue reported in engineering ticket ACM-92309.
This issue is resolved in the following RSA Identity Governance & Lifecycle versions and/or patch levels:
RSA Identity Governance & Lifecycle 7.1.0 P07
RSA Identity Governance & Lifecycle 7.1.1 P02
RSA Identity Governance & Lifecycle 7.2
A zero value is an allowed value for PwdLastSet that indicates the users password has never been set.
