Login Failure Due to Accented Characters in External ID (SSO Integration)

Users may face login errors in PeopleFluent when their federated ID contains accented characters (e.g., è) not recognized by the system, causing SSO failures with messages like “Failed to locate user.” The issue arises from a mismatch between the accented character in the IdP username and the unaccented stored username. 

 

Applicable Product:

  • iPaas

Applicable Release:

  • ANY


Summary:

Users may encounter login errors when their federated ID contains accented characters (e.g., è) that are not recognized by the PeopleFluent system.

Symptoms:

  • User unable to log in via SSO.
  • Error message includes:
    “Failed to locate user for [domain\username]”
  • Request ID example: [DFIN] fcff8b13-62a6-46b2-bc2f-d7df097ffc8b.

Root Cause:

The external ID sent by the Identity Provider (IdP) included an accented character (è) in the username (marième.tester), while the PeopleFluent system stored the username without the accent (marieme.tester). This mismatch caused authentication to fail.

Resolution Steps:

  1. Verify the user’s federated ID:
    • Compare the ID from the IdP with the one stored in PeopleFluent.
  2. Check for hidden characters or accents:
    • Look for special characters like è that may not be visible in standard text.
  3. Update the external ID in PeopleFluent:
    • System rejects copy-pasted accented characters. Use the Alt code method:
      • Press and hold Alt, then type 0232 on the numeric keypad to insert è.
  4. Save changes and retest login.
  5. If accents cannot be supported:
    • Coordinate with the IdP team to remove accented characters from the user record.
