Field Data Mapping
Joomdle lets you leverage some Joomla third party extensions to maintain user profile info.
You can define correspondence of fields in Moodle and Joomla, so Moodle info will always match Joomla.
To use this feature, you first need to enable any Additional data source in Joomdle component configuration. Then you can access Mappings option in Joomdle backend, to define the relations between fields.
