389-adminutil is libraries of functions used to administer directory
servers, usually in conjunction with the admin server. 389-adminutil is
broken into two libraries - libadminutil contains the basic
functionality, and libadmsslutil contains SSL versions and wrappers
around the basic functions. The PSET functions allow applications to
store their preferences and configuration parameters in LDAP, without
having to know anything about LDAP. The configuration is cached in a
local file, allowing applications to function even if the LDAP server
is down. The other code is typically used by CGI programs used for
directory server management, containing GET/POST processing code as
well as resource handling (ICU ures API).
