 - [DBCC CLONEDATABASE (Transact-SQL)](../../../t-sql/database-console-commands/dbcc-clonedatabase-transact-sql.md) throws error on the default installation of the Azure extension for SQL Server. To run the `DBCC CLONEDATABASE`, the Azure extension must be run in [least privilege mode](../configure-least-privilege.md).

+- Database and availability group names with trailing whitespace (for example, `MyDb␠`) aren't supported on instances using binary collations (BIN/BIN2). These objects are skipped by the extension with a warning. On non-binary collations (the default), trailing whitespace is automatically trimmed and the objects are managed normally.
