Managing Duplicate Custodians

When the same person exists more than once, their assets and licences are split across the copies and no report about them is right. Manage Duplicate Custodians finds the likely duplicates and merges them into one person.

Open the People Dashboard and choose the Duplicates tab.

The Manage Duplicate Custodians list, showing candidate duplicates with the reason each was matched, their primary login, email and asset count

Reading the List

People that look like the same human appear together. Each row is one person record, and a pair or group of rows is one suspected human:

Column Meaning
Name The person's name as held on that record
Matched On Why this record was flagged — see below
Primary Login Their main username
EMail Their email address
Logins Known How many identities are recorded against this record
xAssets User Whether this person can log in to xAssets
Assets How many assets they hold
Department / Status Context for deciding which record to keep

Matched On is the column to read first, because it tells you how much to trust the suggestion. It takes one of three values:

Matched On Means Trust
Same login Two records carry a username that resolves to the same person, even if the two usernames are spelled differently High — this is almost always the same human
Same email Two records share an email address High — people rarely share a mailbox
Same name Two records carry the same name, and nothing stronger links them Check before merging — two people can share a name

Work down that order. Same login and Same email can usually be merged on sight. Same name deserves a look at the department, location and asset list first, because merging is not something you can cleanly undo.

Assets and Logins Known tell you which record is the substantial one. Usually one record has the history and the others are thin copies created by an integration that did not recognise the person.

Merging

  1. Tick the records that are the same person. Include the one you want to keep.
  2. Choose Deduplicate Selected Custodians.
  3. Confirm when prompted.

Everything the duplicates hold — assets, licence assignments, history, identities — moves onto the surviving record, and the redundant records are removed. The identities move too, which is the part that stops the duplicate coming straight back: whichever username the integration was using is now recorded against the surviving person, so the next run matches it.

Merge one group at a time and check the result. It is not reversible.

If Duplicates Keep Coming Back

Merging fixes the records you have. If new duplicates appear on the next integration run, something upstream is still not matching:

Symptom Likely cause
A specific person duplicates every run The integration sends a username not recorded against them — add it by hand via Show Logins
Many duplicates from one integration That integration is allowed to create people when it should not be — see Custodian Matching and Integration Authority
Duplicates differing only by name spelling Name matching is off, and their usernames genuinely differ — record the second username as an identity
Two genuinely different people merged They share a name and name matching was on — see Custodian Identities

The durable fix is nearly always on the identity side rather than repeated merging. See Custodian Identities.

Before You Start

  • Run your integrations first. Merging before a sync means merging again afterwards.
  • Do the obvious ones first — matches on email or username. Leave name-only matches until you have checked them.
  • Watch the licence counts. Duplicates inflate per-user licence consumption, so a merge should reduce it. If your seat count does not fall after a merge, the duplicates were not consuming seats and the saving is elsewhere.
