Samba is a Brazilian musical genre and dance style originating in Brazil, with its roots in Africa via the West African slave trade and African religious traditions, particularly Angola and the Congo. Although there were various forms of samba in Brazil in the form of various popular rhythms and regional dances that originated from the drumming, samba as music genre is seen as a musical expression of urban Rio de Janeiro, then the capital of Imperial Brazil.

Samba is a free software re-implementation of the SMB/CIFS networking protocol, and was originally developed by Andrew Tridgell. Samba provides file and print services for various Microsoft Windows clients and can integrate with a Microsoft Windows Server domain, either as a Domain Controller (DC) or as a domain member. As of version 4, it supports Active Directory and Microsoft Windows NT domains.
