Fully qualified name is a name in the form of user@domain. I.e. if you 
have [domain/mydomain] in /etc/sssd/sssd.conf the fully qualified name 
will be number@mydomain.

If they are used to login with their email address, you could also 
switch name attribute to the email address attribute if it is in LDAP.

See ldap_user_name in `man sssd-ldap` and use_fully_qualified_names and 
full_name_format in `man sssd.conf`.
