    Bug Description: init script modification needed for kerberos auth
    Reviewed by: nhosoi (Thanks!)
    Fix Description: I just took Simo's initial patch and ran with it.  The initconfigdir parameter is the directory containing the config file for the init script.  configure will first try to use $(sysconfdir)/sysconfig, then $(sysconfdir)/default (Solaris and Debian, among others), then the package config directory (the default on HP-UX), for this parameter.  The init script and startup script will look in the initconfigdir to find the init config file to source.  For directory server, an instance specific file can be used, named e.g. dirsrv-localhost which will apply to the slapd-localhost instance only.
    A default init config file is provided for dirsrv and dirsrv-admin, with some examples of how it could be used.
    Platforms tested: RHEL5 x86_64
    Flag Day: Yes - autotool file changes
    Doc impact: Yes.  We will need to document how the user can supply environment to the servers at startup time without having to edit the init scripts or the startup scripts.
    QA impact: should be covered by regular nightly and manual testing
    New Tests integrated into TET: none
