====== eBiss Update with MSSQL =====

Microsoft SQL Server supports two authentication modes: Windows authentication mode and mixed mode.

{{:images:sign_warning.png?nolink|}}**Note:** Authentication mode details: https://docs.microsoft.com/de-de/dotnet/framework/data/adonet/sql/authentication-in-sql-server

For installations and updates on MSSQL Server the following permissions must be considered:

  - the user who performs the installation or update **must be the DBO**((Database Owner Without DBO, new tables are created in other schemas.))
  - Users must have read and write permissions((Whenever "integrated security" login is used, special attention should be paid to the authorization concept here.))
