MDM users are managed at two levels: from Talend Administration Center and from MDM. The information of an MDM user (for example, login, password, and assigned system roles) for accessing Talend MDM is maintained by Talend Administration Center, while its corresponding information (for example, language, and assigned custom roles) for using Talend MDM is maintained by the web user interface.
For more information about how to add MDM users in Talend Administration Center, see Talend Administration Center User Guide.
