Sharity mounts shares exported by Windows, Samba, and other SMB/CIFS servers in the file system of Unix computers. It implements Resource Browsing, which is similar to the Windows Network Neighborhood (Netbios Workgroups and Active Directory), NTLM, NTLMv2, and Kerberos authentication, Microsoft's Distributed File System (DFS), and manipulation of Access Control Lists (ACLs).
Sharity-Light for Linux is derived from smbfs, but runs as a user level program, not in the kernel. It is roughly the opposite of Samba since it's a client for the Lanmanager protocol. Sharity-Light lets you mount drives exported by Windows (f.Workgroups/95/NT), Lan Manager, OS/2 etc. on Unix machines. The former name of this application was "rumba".
