I’m familiar with the existing configurations, but unfortunately, they don’t address my specific objective. In our discourse system, we employ a Single Sign-On (SSO) mechanism for login, and users don’t have permission to update their usernames. The registration pop-up is also hidden.
Currently, the username is generated from the ‘name’ field, which includes both the first and last names. My goal is to have the username reflect only the user’s first name.
Is this achievable, and are there any plugins or scripts available to facilitate this customization?
