Handle Duplicate Users During CSV Import

Explain the administrator choices to flag-and-skip duplicates or skip automatically, plus how preview protects against accidental duplicate account creation.

This guide follows the accepted QC Frontend User Manager 2.0.4 implementation and applies to Pro+; administrator and frontend manager. QCFUM delegates selected Joomla user-onboarding and management workflows without making frontend staff Joomla backend administrators. When older manuals or walkthrough wording differs from the current source or accepted keyless-entitlement behavior, the current implementation takes precedence.

Before You Begin

• Confirm Effective Pro/Max access before relying on CSV, approval, or temporary-access features.
• Preview imports before committing them and use a small controlled test first.
• Keep Scheduled Automation healthy whenever temporary access already exists, even if commercial automation is turned off.

Step-by-Step Workflow

1. Open the Pro+ Import tab from the unified Dashboard.
2. Start from the QCFUM sample CSV or confirm required headers and the administrator row/upload limits.
3. Choose the default Direct Create or Invite Link mode plus valid default Profile/Invite Pack where needed.
4. Upload the CSV and run Preview; do not commit before reviewing row-level validation.
5. Correct invalid/duplicate/unauthorized rows or intentionally accept the supported handling choice.
6. Commit the import only after Preview matches the intended onboarding result.
7. Review the import summary, Recent Users/Tracker/invitations, approval state, and email-delivery outcome.

CSV Intake Reference

Always use Preview before committing a production import. A valid upload can still contain rows that QCFUM refuses because of duplicate identity, invalid workflow selection, unavailable Profile/Pack, group protection, or current tier/allowance limits.

The administrator choices to flag-and-skip duplicates or skip automatically,

Explain the administrator choices to flag-and-skip duplicates or skip automatically, plus how preview protects against accidental duplicate account creation. In QCFUM 2.0.4, this must be evaluated together with the current Effective tier, the Joomla/QCFUM permissions of the acting account, and target/workflow safeguards. QCFUM is designed to fail closed around protected users and sensitive actions rather than trusting the presence of a frontend button as authorization.

For Handle Duplicate Users During CSV Import, test the exact workflow with a safe non-administrator account and a deliberately chosen target. QCFUM’s frontend presentation is not the authorization boundary: a control can be visible while the server still refuses an unsafe target, an unavailable tier, an invalid workflow state, or a group change that violates administrator-defined safeguards.

How This Fits into QCFUM

CSV, durable approvals, and temporary-access expiration add scale and control. Security enforcement is deliberately separated from optional commercial automation.

A reliable QCFUM configuration keeps Joomla authoritative for real user accounts while QCFUM owns the delegated workflow, attribution, approval, automation, and safety rules around those accounts. This separation matters during upgrades and downgrades: preserving QCFUM records does not mean every preserved premium feature remains usable at a lower Effective tier.

Security and Data-Protection Notes

• Use least privilege for menu access and QCFUM ACL; grant staff only the actions required for their role.
• Never share passwords, invite tokens, API credentials, or private account data in screenshots, support requests, or custom email content.
• Treat Super Users and equivalent administrative-capability accounts as protected even when a UI configuration appears permissive.
• Verify destructive or access-changing actions with a safe test account before enabling them for production staff.
• Remember that uninstall/reinstall is not a supported method for wiping QCFUM business data or resetting entitlement/preview history.

Verify the Result

• The resulting Joomla user/group state matches the intended QCFUM workflow.
• A protected or out-of-scope user remains protected when tested with the delegated staff account.
• Preview/summary counts match the intended rows and no password column or unauthorized workflow slipped through.
• Reload the real frontend/Administrator view rather than relying only on a saved form message.
• Repeat the critical test using the exact non-Super-User group that will operate the workflow.

Common Mistakes to Avoid

• Skipping Preview or adding a password column to the CSV.
• Testing only as Super User instead of the actual delegated staff group.
• Changing multiple security/workflow settings at once during troubleshooting, making the real cause difficult to identify.

Troubleshooting

• If a control or tab is missing, check Effective tier, QCFUM ACL, menu access, and feature configuration before assuming installation damage.
• If a user cannot be selected or changed, check protected groups/IDs, core administrative protection, visibility/editability rules, destination-group rules, and the delegated manager’s exact permissions.
• If onboarding stalls, inspect the stored workflow status (invite, approval, import, temporary access) rather than deleting the record and starting over immediately.
• If automation does not run, verify Joomla Scheduled Tasks and distinguish the hourly Entitlement Revalidation task from the separately configured Scheduled Automation task.
• If email does not arrive, verify Joomla mail transport independently, then inspect QCFUM template publication, recipient/address, queue state, and retry eligibility.

Operational Best Practice

Keep onboarding definitions simple enough that staff can select the correct Profile/Pack without guessing. Test every delegated workflow with the real staff Joomla group, keep entitlement/tasks healthy, and preserve an Administrator recovery path. When changing user-management safeguards, verify both a target that should be allowed and a protected target that must still be refused.
