For an 802.1X network that isn't EAP-TLS and has unique credentials associated with each user, each user must manually connect to the 802.1X network the first time they sign in on that device. This manual setup is required even if you enable auto-connect setting and configure the credentials with variables. After the user connects manually for the first time, the credentials are stored in their profile on the device. On future logins, they are automatically connected to the network.
