Duo Unix new users

After deploy pam_duo on RedHat I added a new local user in the server and DUO cloud but when I try to log into RedHat with the new user it request me enroll my user.
Someone know why DUO cant see my new user ?
I can´t log in with new users , It just work with users created before installing pam_duo

Does the Red Hat username match the user already created in Duo exactly? If not , you could try adding the username Red Hat is sending as a username alias for the user you already created in Duo. See the user field table here for more info.
