       /usr/lib/openldap/slapd   [-[4|6]]  [-d  debug-level]  [-f
       slapd-config-file] [-h URLs] [-n  service-name]  [-s  sys­
       log-level] [-l syslog-local-user] [-r directory] [-u user]
       [-g group] [-t]


       Slapd is the stand-alone LDAP daemon. It listens for  LDAP
       connections on any number of ports (default 389), respond­
       ing to the LDAP operations it receives over these  connec­
       tions.   slapd  is typically invoked at boot time, usually
       out of /etc/rc.local.  Upon startup, slapd normally  forks
       and  disassociates  itself from the invoking tty.  If con­
       figured in  /etc/openldap/slapd.conf,  the  slapd  process
       will  print  its  process  ID  ( see getpid(2) ) to a .pid
       file, as well as the command line options  during  invoca­
       tion  to  an  .args file ( see slapd.conf(5) ).  If the -d
       flag is given, even with a zero argument, slapd  will  not
       fork and disassociate from the invoking tty.

       Slapd  can be configured to provide replicated service for
       a database with the help of slurpd,  the  standalone  LDAP
       update replication daemon.  See slurpd(8) for details.

       See  the "OpenLDAP Administrator's Guide" for more details
       on slapd.


       -4     Listen on IPv4 addresses only.

       -6     Listen on IPv6 addresses only.

       -d debug-level
              Turn on debugging as defined  by  debug-level.   If
              this  option  is  specified, even with a zero argu­
              ment, slapd will not fork or disassociate from  the
              invoking terminal.  Some general operation and sta­
              tus  messages  are  printed  for   any   value   of
              debug-level.  debug-level is taken as a bit string,
              with each bit corresponding to a different kind  of
              debugging  information.   See <ldap.h> for details.
              Remember that if you turn on packet logging,  pack­
              ets containing bind passwords will be output, so if
              you redirect the log to a logfile, that file should
              be read-protected.

       -s syslog-level
              This  option  tells  slapd  at what level debugging
              statements should be logged to the syslog(8) facil­

       -n service-name

       -h URLlist
              slapd will by default serve ldap:/// (LDAP over TCP
              on  all interfaces on default LDAP port).  That is,
              it will bind using INADDR_ANY and port 389.  The -h
              option  may  be  used  to  specify  LDAP (and other
              scheme) URLs to serve.  For example,  if  slapd  is
              given    -h    "ldap://    ldaps:///
              ldapi:///" , It will bind for  LDAP,
      for  LDAP  over TLS, and LDAP over IPC
              (Unix domain  sockets).   Host  represents
              INADDR_ANY.   A  space  separated  list  of URLs is
              expected.  The URLs should be of LDAP (ldap://)  or
              LDAP   over   TLS   (ldaps://)  or  LDAP  over  IPC
              (ldapi://) scheme without a DN  or  other  optional
              parameters,  except  an  experimental  extension to
              indicate the permissions of the underlying  socket,
              on  those  OSes  that  honor them.  Support for the
              latter two schemes depends on  selected  configura­
              tion  options.   Hosts  may be specified by name or
              IPv4 and IPv6 address formats.  Ports, if specfied,
              must  be  numeric.  The default ldap:// port is 389
              and the default ldaps:// port is 636.   The  socket
              permissions  for LDAP over IPC are indicated by "x-
              mod=-rwxrwxrwx", "x-mod=0777" or "x-mod=777", where
              any of the "rwx" can be "-" to suppress the related
              permission (note, however, that sockets only  honor
              the  "w"  permission),  while any of the "7" can be
              any legal octal digit, according to chmod(1).

       -r directory
              Specifies a chroot "jail"  directory.   slapd  will
              chdir(2)  then  chroot(2)  to  this directory after
              opening listeners but before reading any configura­
              tion file or initializing any backend.

       -u user
              slapd  will  run slapd with the specified user name
              or id, and that user's supplementary  group  access
              list  as  set  with initgroups(3).  The group ID is
              also changed to this  user's  gid,  unless  the  -g
              option is used to override.

       -g group
              slapd will run with the specified group name or id.

       Note that on some systems,  running  as  a  non-privileged
       user  will  prevent  passwd  back-ends  from accessing the
       encrypted passwords.  Note also that any  shell  back-ends
       will run as the specified non-privileged user.

       -t     slapd will read the configuration file (the default
            /usr/lib/openldap/slapd -f /var/tmp/slapd.conf -d 255

       To  test whether the configuration file is correct or not,

            /usr/lib/openldap/slapd -t
