H1: Running slapd

{{Slapd}}(8) is designed to be run as a stand-alone server.  This allows
the server to take advantage of caching, manage concurrency issues
with underlying databases, and conserve system resources.  Running
from {{inetd}}(8) is {{NOT}} an option.


H2: Command-Line Options

{{I:Slapd}} supports the following command-line options.

E: -d <level> | ?

This option sets the slapd debug level to <level>. When level is a
`?' character, the various debugging levels are printed and slapd
exits, regardless of any other options you give it. Current
debugging levels are

E:     1 trace function calls
E:     2 debug packet handling
E:     4 heavy trace debugging
E:     8 connection management
E:    16 print out packets sent and received
E:    32 search filter processing
E:    64 configuration file processing
E:   128 access control list processing
E:   256 stats log connections/operations/results
E:   512 stats log entries sent
E:  1024 print communication with shell backends
E:  2048 print entry parsing debugging
E: 65535 enable all debugging

You may enable multiple levels by specifying the debug option
once for each desired level.  Or, since debugging levels are
additive, you can do the math yourself. That is, if you want
to trace function calls and watch the config file being
processed, you could set level to the sum of those two levels
(in this case, {{EX: -d 65}}).  Or, you can let slapd do the
math, (e.g. {{EX: -d 1 -d 64}}).  Consult {{EX: <ldap.h>}} for
more details.

Note: slapd must have been compiled with {{EX:-DLDAP_DEBUG}}
defined for any debugging information beyond the two stats levels
to be available.

E: -f <filename>

This option specifies an alternate configuration file for slapd.

E: -p <port>

This option specifies an alternate TCP port on which slapd should
listen for connections. The default port is 389.


H2: Starting slapd

In general, slapd is run like this:

E: 	$(ETCDIR)/slapd [<option>]*

where ETCDIR has the value you gave in the Make-common file
during the pre-build configuration, and <option> is one of the
options described below. Unless you have specified a debugging
level, slapd will automatically fork and detach itself from its
controlling terminal and run in the background. Any of the options
given above can be given to slapd to point it at a different
configuration file, listen on another port, etc.

H2: Stopping slapd

To kill off slapd safely, you should give a command like this

E: 	kill -TERM `cat $(ETCDIR)/slapd.pid`

Killing slapd by a more drastic method may cause its LDBM
databases to be corrupted, as it may need to flush various buffers
before it exits. Note that slapd writes its pid to a file called 
{{EX: slapd.pid}} in the {{EX: ETCDIR}} you configured in 
{{EX: Make-common}}. You can change
the location of this pid file by changing the {{EX: SLAPD_PIDFILE}}
variable in {{EX: include/ldapconfig.h.edit}}.

{{I: Slapd}} will also write its arguments to a file called 
{{EX: slapd.args}} in the {{EX: ETCDIR}} you configured 
in {{EX: Make-common}}. You can change the
location of the args file by changing the {{EX: SLAPD_ARGSFILE}}
variable in {{EX: include/ldapconfig.h.edit}}.
