Samba-AD migration at BCEAO – Central Bank
The Central Bank of West African States is a network of 24 agencies located in the main cities of the West African economic and monetary zone. The bank and its regional agencies are responsible for issuing banknotes in CFA francs and for collecting and destroying used notes. Finally, the BCEAO is responsible for issuing the loans of its 8 member states, as does the ECB in Europe. Each of the 24 agencies operates an office automation domain based on Samba3 software, a highly critical and rapidly obsolescent software.

The Central Bank of West African States is a network of 24 branches located in the main cities of the West African economic and monetary zone. The bank and its regional branches are responsible for issuing banknotes in CFA francs, collecting and destroying used banknotes. Finally, the BCEAO is responsible for issuing the bonds of its 8 Member States, as the ECB does in Europe. Each of the 24 agencies operates an office automation domain based on the Samba3 software, a highly critical and rapidly obsolete software.
In the context of the Samba-AD migration, it was a question of :
- Merge office networks to allow VIPs to connect, regardless of the regional bank visited
- Improve network security by implementing 802.1x and Active Directory
- Converge to market technical standards
- Continue with Samba because it has always worked for BCEAO
Extract from the project report :BCEAO mandated TRANQUIL IT to accompany its teams in :
- Samba3-PDC-NT4 Windows domain migration to Samba Active Directory technology,
- rename the main domain
- merge all 26 domains into a single BCEAO domain. Denis CARDON, a graduate engineer from ENS of Mines of Nancy and CEO of TRANQUIL IT, and Yvan KARMOUTA intervened in Dakar from 14th September to 11th October 2015 (Yvan returned to France on 3rd October). BCEAO has a long history of investing in IT technologies of the free world. This strategy has the advantage of rely on local skills development and reduces the importation of technologies without the associated knowledge transfer. Samba3 domain technologies are based on Windows Server NT4 running, with several improvements to allow better load handling and guarantee greater security. However, NT4 quickly becomes obsolete. For example, the latest Windows 10 version can only be integrated into a Samba3-NT4-PDC domain if the old CIFS/ SMB1 protocol is forced to be used. The choice to switch to Active Directory was therefore a logical one. It is also one of the concerns of a large number of French administrations that have also made the historic choice of Samba. The choice of Samba4-AD rather than MSAD is not the most obvious choice and many structures question this option.
