    $ cd <installation directory>/bin/slapd/server
    $ ./ns-slapd -V -D <instance-directory>
    Sun Java(TM) System Directory Server/5.2    

On 64-bit Solaris:

    $ cd <installation directory>/bin/slapd/server/64
    $ ./ns-slapd -V -D <instance-directory>
    Sun Java(TM) System Directory Server/5.2

On 64-bit HP-UX:

    $ cd <installation directory>/bin/slapd/server/pa20_64
    $ ./ns-slapd -V -D <instance-directory>
    Sun Java(TM) System Directory Server/5.2

On Windows systems:

    >cd <installation directory>/bin/slapd/server
    >slapd.exe -V -D <instance-directory>
