  14        A dbm database served by the NIS server is called a NIS map. A NIS
  15        domain is a subdirectory of /var/yp that contains a set of NIS maps on
  16        each NIS server.
  17 
  18 
  19        Standard nicknames are defined in the file /var/yp/nicknames. These
  20        names can be used in place of the full map name in the ypmatch and
  21        ypcat commands. Use the command ypwhich -x to display the current set
  22        of nicknames. Use the command ypwhich -m to display all the available
  23        maps. Each line of the nickname file contains two fields separated by
  24        white space. The first field is the nickname, and the second field is
  25        the name of the map that it expands to. The nickname cannot contain a
  26        ".".

  28    NIS to LDAP (N2L)
  29        If the /var/yp/NISLDAPmapping configuration file is present, the NIS
  30        server operates in NIS to LDAP (N2L) mode. In this mode, NIS maps are
  31        stored in a new set of DBM files, prepended by the LDAP_ prefix, at
  32        /var/yp/domainename. These files are used as a cache backed by
  33        information from an LDAP server. Additional DBM files are created in
  34        the same directory to hold the cache's TTL values.
  35 
  36 
  37        N2L mode enables NIS clients to be supported in an LDAP environment.
  38 
  39 
  40        In N2L mode, the old style DBM files, NIS source files, and the
  41        ypmake(1M) utility have to role. They are retained to enable easy
  42        conversion back to the traditional mode, if required.
  43 
  44    Converting from N2L to Traditional NIS
  45        When NIS is operating in N2L mode, it uses a new set of NIS maps with
  46        an LDAP_ prefix, based on the contents of the LDAP DIT. The NIS source
  47        files are unused and become out of date. If you wish to convert back to
  48        the traditional NIS mode, the N2L configuration file should be deleted.
  49        The system will then return to using the standard map files.
  50        Optionally, the N2L mode map files, /var/yp/*/LDAP_* can also be
  51        deleted.
