Need to configure Offline Authentication in Ubuntu

Hello All,

Good morning !!!

Hope you all are well, Today i want to share one little issue with you for Offline Authentication with OpenLDAP server,

In this scenario, I have configured OpenLDAP Server on Centos7 and another side i have configured Ubuntu as a client system,

I had done configuration by using SSSD utility on client system, and i got authenticated with my OpenLDAP server from my client system,

Now, i want to configured Offline Authentication for OpenLDAP users, Because my most of users are working from home in that case they all are unable to communicate with OpenLDAP Server Because my OpenLDAP server is in Local Area Network, So, i want to configured Offline Authentication Mode for all OpenLDAP users...

Hope you understand my question and requirements,

Could you please, help me in this case

Thank You,
