Hi @mukul1409 - are you able to validate at your end to ensure you have users table under information_schema. Even if I tried to check in Databricks Free edition where I am the account admin and not able locate this table. Requesting you, please validate once to check this? See the screenshot from Databrick Free Edition.

I am able to see all other tables under system database, so need to understand whether the issue is with my end or these tables are depreciated. 

Regards - San
