Files in
netid format are rare. One lives in the NIS map
netid.byname. The format is rather simple. Each row consists of two items, a key and a value. When created by
mknetid(8) there are three kind of records.
The first type is information about which gids a uid has:
unix.<uid>@<yp-domain> <uid>:<gid>,<gid>
The second type has informations about hosts:
unix.<hostname>@<yp-domain> 0:<hostname>
The third type is records from a
netid file other than the two types above.
