The session management interface of the net session command uses the old RAP method to obtain the list of connections to the Samba server, as shown here:

root#  net rap session -S MERLIN -Uroot%not24get
Computer             User name            Client Type        Opens Idle time
------------------------------------------------------------------------------
\\merlin             root                 Unknown Client         0 00:00:00
\\marvel             jht                  Unknown Client         0 00:00:00
\\maggot             jht                  Unknown Client         0 00:00:00
\\marvel             jht                  Unknown Client         0 00:00:00

A session can be closed by executing a command as shown here:

root#  net rap session close marvel -Uroot%not24get
