Ensure SQL Authentication is not used in contained databases
MediaNivel 1Automatizadamssql
Descripción
Contained databases do not enforce password complexity rules for SQL Authenticated users. Iterates contained databases only. Default: SQL Authenticated users (USER WITH PASSWORD authentication) are allowed in contained databases. Runs one sqlcmd query with its defaults (Windows authentication to the local default instance); set SQLCMDSERVER, SQLCMDUSER and SQLCMDPASSWORD for another instance or SQL authentication. Needs VIEW SERVER STATE / sysadmin-level read access.
