idAttribute property
Determines which attribute to use as the user's identity after they are authenticated.
This is distinct from the loginAttribute field to allow users to login with a username, but then have their actual identifier be an email address or full Distinguished Name (DN). For example, setting loginAttribute to "sAMAccountName" and identifierAttribute to "userPrincipalName" would allow a user to login as "bsmith", but actual RBAC policies for the user would be written as "bsmith@example.com". Using "userPrincipalName" is recommended since this will be unique for each user. This defaults to "userPrincipalName".
Optional.
Implementation
core.String? idAttribute;
