Autofs searches a series of maps to navigate through the network. Maps are files that contain information such as the password entries of all users on a network or the names of all host computers on a network. Effectively, the maps contain network-wide equivalents of UNIX administration files. Maps are available locally or through a network name service such as NIS or NIS+. You create maps to meet the needs of your environment by using the Solstice System Management Tools. See Modifying How Autofs Navigates the Network (Modifying Maps).
