Although this Topic is under the IdentityNow (IDN) category, this Connector Attribute is not valued by IdentityNow and is only valued by IIQ, (as per the Active Directory Connector - FAQ and Troubleshooting , “IdentityIQ Troubleshooting” Section.
In point of fact, SailPoint do not even recommend using this Connector attribute as this does not solve the underlying issue that is causing this warning to be posted, it only prevents the warning messages from being posted.
Cyclic group hierarchy will have an effect on IDN, IIQ and Active Directory performance, and this message should be considered as a Canary warning in order to address the links between the groups in the Active Directory Domain.
