Will the IAM Service affect my local accounts?

No, there is no requirement that you make any changes to your user accounts within your LEA. The UID number however is the login for cloud-based services such as HomeBase and other NCEdCloud IAM apps (should you choose to adopt them).  Whether an LEA chooses to use NCEdCloud IAM accounts within their local district services is up to you. If it is of interest to do so, it is possible the NCEdCloud IAM’s CDLR service could help facilitate that.
