and remove:

Claim rule:  
Name → username  
this works but Asking user name suggesion during the login time.  
any idea how to avoid that ??

is there any way to Sync LDAP user and authenticate with SAML ? this way it works with SAML and does not ask for username suggesion during login.  
i know this is funny requirment but there is need to go with this.
