Double hmmm. The only file other than DB_CONFIG was alock, due to a 
previous run.

A clean invocation with the options above:

  5996      1 slapd    RET   write 1024/0x400
  5996      1 slapd    CALL  lseek(8,0,0,0)
  5996      1 slapd    RET   lseek 0
  5996      1 slapd    CALL  fcntl(8,8,0x7f7fffffcf40)
  5996      1 slapd    RET   fcntl 0
  5996      1 slapd    CALL  __stat50(0x7f7ffb0d1a60,0x7f7fffffd5a0)
  5996      1 slapd    NAMI  "/var/openldap/openldap-data/DB_CONFIG"
  5996      1 slapd    RET   __stat50 0
  5996      1 slapd    CALL  __stat50(0x7f7fffffd100,0x7f7fffffd500)
  5996      1 slapd    NAMI  "/var/openldap/openldap-data/__db.001"
  5996      1 slapd    RET   __stat50 -1 errno 2 No such file or directory
  5996      1 slapd    CALL  getpid
  5996      1 slapd    RET   getpid 5996/0x176c, 20291/0x4f43
  5996      1 slapd    PSIG  SIGSEGV SIG_DFL: code=SEGV_MAPERR, 
addr=0x30, trap=
6)

Now it's been a while but I am pretty sure it should populate the directory?

Thanks,
