 - OpenLDAP is highly flexible. Has code-reliant functionality which doesn’t lock users into predetermined workflows; rather, we can manipulate the software to our exact needs.
 
 ## Cons
-- Directory configuration and management are manual.
+- Directory configuration and management are manual. Hence it is more time consuming and has a higher learning curve.
+- OpenLDAP is a command-line application. However there are multiple LDAP browsers available which can be used in case a UI is required. Few of them listed below:

+## Samba
+-  Samba runs on Unix platforms, but speaks to Windows clients like a native. It allows a Unix system to move into a Windows "Network Neighborhood" without causing a stir. Windows users can happily access file and print services without knowing or caring that those services are being offered by a Unix host.
+- Samba is an open source CIFS implementation. CIFS or Common Internet File System is a protocol suite used to share files remotely via IP. 
+- Samba allows for a Linux server to act as a Domain Controller. By doing so, user credentials on the Windows domain can be used instead of needing to be recreated and then manually kept in sync on the Linux server.
+- A domain controller is a server that manages network and identity security, effectively acting as the gatekeeper for user authentication and authorization to IT resources within the domain.
