Working with NIS
In networks where NIS and NFS are in use, it is common for
users’ home directories to be mounted over the
network by NFS. If a Samba server being used to authenticate user
logons is running on a system with NFS-mounted home directories
shared with a [homes] share, the additional
overhead can result in poor performance—about 30% of normal
Samba speed.
Samba has the ability to work with NIS and NIS+ to find the
server on which the home directories actually reside so that they can
be shared directly from that server. For this to work, the server
that holds the home directories must also have Samba running, with a
[homes] share of its own.
