What are Contained Databases
• Isolated from other DBs and the SQL
Server Instance
• Majority of the metadata that describes the
database is maintained within the
database
• Users in contained DBs no longer
associated with SQL Server Logins
• Simplified security model
• Portability
Authentication
• Contained User
– Contained User with Password
– Windows Principals
• Enable Contained DB Authentication sp_configure 'contained database authentication', 1;
• Disable Contained DB Authentication sp_configure 'contained database authentication', 0;
