Duplicate Data in Configurable User Synchronisation

What

If you have manually created Users and add them to the source data for the Configurable User Synchronisation cron job, then the job will try to create these as new Users.

Job log
Creating User with external id 23969
INFO: Creating new User
ERROR: Encountered a problem while transferring values
----------------- Validation error -----------------
Username has the same value as other content
Exception details
Validation of content 'User(id=<null>, username=xxx)' failed:
Validation errors:
username: ValidationResult [code=validation.text.unique, args=null, nestedProperty=null, value=m.gotte], propertyPath: username
INFO: Done!

Why

  • The synchronisation can't find the User because it looks for synchronised User with a source ID.
  • In these cases you would have to remove the user in Pure and add it again through the synchronisation. Read more about how to do this in Updating Users in Pure (Master List vs. Synchronisation)
