Ticket #47935 - Error: failed to open an LDAP connection to host 'example.org' port '389' as user 'cn=Directory Manager'. Error: unknown.
    
    Description: "slapd started." message is logged prior to calling
    PR_Listen on configured ports as well as creating a pid file.  It
    confuses the install script that relies on the keyword to determine
    if the server is ready or not.
    
    This patch moves the "slapd started." logging code after calling
    PR_Listen and creating a pid file.
