automount Frequent file system
access to a directory
may request
automount
information about a
network file system. A
positive AutoFS cache
greatly reduces
LDAP-UX Client
response time while
retrieving the
automount data.
Whenever a user
attempts to access a
directory that does not
exist on the physical
file system, the
AutoFS system is
called to determine if
that directory is
available via the
network through
AutoFS. A negative
AutoFS cache is
critical to assure that
malfunctioning
applications do not
place redundant bogus
requests on the
directory server.
For the positive
AutoFS cache, an
alteration of the
automount maps
will sometimes not
appear
immediately.
During this
expiration
window, a network
file system may be
granted access,
when in fact the
automount map
should have
unmounted from a
network file
system.
For the negative
AutoFS cache, an
alteration of the
automount maps
will sometimes not
appear
immediately.
During this
expiration
window, a user
attempting to
access a network
file system may be
denied access,
when in fact the
automount map
should have set up
a network file
system mount.
