Currently Phone field for Users seems to be useless in SSO authentication mode (on-premises):
1. There is no possibility to define this attribute in csv import file.
2. There is no possibility to map this attribute with corresponding SAML responce entity from IdP.
We need both options because country code in the Phone number is the best indicator for us to see if user is Onshore or Offshore and grant him/her with corresponding permissions in Octane workspaces following the GDPR.
