How to change user email addresses

Good day I trust you are well

I would like to find out how I can change user sign in email addresses.

We are changing our email addresses to a new domain.

I logged into our Sonarqube account and changed my email address to the new domain but when I logout and try to sign in again the username is still the old email address.
I would like to change my username to the new email address.
Kind regards

Michael,

It sounds like you have authentication delegated to LDAP, is that correct?
