Directory data syncronization between IdP and FW is not supported
At this time, FileWave IDP integration is limited to only FileWave Admin authentication and Apple device enrollment. Directory data synchronization (and custom fields) between the IdP source and FileWave is not supported at this time, but will be added in a future release. In the meantime, current LDAP(S) synchronization can be used as a stop-gap to achieve the same result.
