You may have noticed that Password Manager creates and stores separate version nodes on the specific attribute (default: Comment) of the user’s object. At no point the product removes old version entries.
This may become an issue after a number of upgrades have been performed, specifically relating to the network utilization for replication and AD storage.
This is by design. Entries related to old versions may be required when migrating from one version to the next.
Since this is only necessary during the migration process, we have created an enhancement request (TF00470281) to include a functionality that would allow those old entries from being removed once the update/migration process is complete.
Manually remove old/stale entries from the specific attibute (default: Comment).
The product team will evaluate the request and this feature may become available on a future release of the product.
