Re: [SLUG] NIS problem - non-existent map

[Rodolfo Martínez <rmtzcx@xxxxxxxxx>]

Hi Nigel,

Add this line to the /etc/nsswitch.conf file in the client:

shadow:    files  [NOTFOUND=return]

The client will only look at the local shadow file, if the entry is
not there, it will stop searching for it.
