History
NetInfo was introduced in NeXTSTEP version 0.9, and replaced both the Unix system configuration files and Sun Microsystems' Network Information Service (Yellow Pages) on NeXT computers. It immediately caused controversy, much unfavorable. Not only was NetInfo unique to NeXT computers (although NeXT later licensed NetInfo to Xedoc, an Australian software company who produced NetInfo for other UNIX systems), DNS queries went through NetInfo. This led to a situation where basic tasks such as translating a UNIX UID to a user name string would not complete because NetInfo was stalled on a DNS lookup. At first, it was possible to disable NetInfo and use the Unix system files, but as of NeXTSTEP version 2 disabling NetInfo also disabled DNS support. Thus, NeXT computers became notorious for locking a user out of everyday tasks because a DNS server had stopped responding.
The Mac OS X version of NetInfo remedied this (and many other problems), but due to the early problems, NetInfo never took over the world of Unix system configuration.
Apple has moved away from using NetInfo towards LDAP, particularly in Mac OS X Server. . Mac OS X v10.4 is the last version to support Netinfo. Beginning with Mac OS X v10.5, Netinfo has been completely phased out and replaced by a new local search node named dslocal, which files are located in /var/db/dslocal/ and are standard property list (XML-based) files.

Famous quotes containing the word history:
“The whole history of civilisation is strewn with creeds and institutions which were invaluable at first, and deadly afterwards.”
—Walter Bagehot (1826–1877)
“Literary works cannot be taken over like factories, or literary forms of expression like industrial methods. Realist writing, of which history offers many widely varying examples, is likewise conditioned by the question of how, when and for what class it is made use of.”

“The history of a soldier’s wound beguiles the pain of it.”
