slapdn — Check a list of string-represented LDAP DNs based on schema syntax


/usr/sbin/slapdn [-d debug-level] [-f slapd.conf] [-F confdir] [-N|-P] [-o option[=value]] [-v] DN [...]


Slapdn is used to check the conformance of a DN based on the schema defined in slapd(8) and that loaded via slapd.conf(5). It opens the slapd.conf(5) configuration file or the slapd-config (5) backend, reads in the schema definitions, and then parses the DN list given on the command-line.


-d debug-level

enable debugging messages as defined by the specified debug-level; see slapd(8) for details.

-f slapd.conf

specify an alternative slapd.conf(5) file.

-F confdir

specify a config directory. If both -f and -F are specified, the config file will be read and converted to config directory format and written to the specified directory. If neither option is specified, an attempt to read the default config directory will be made before trying to use the default config file. If a valid config directory exists then the default config file is ignored.


only output a normalized form of the DN, suitable to be used in a normalization tool; incompatible with -P.

-o option[=value]

Specify an option with a(n optional) value. Possible generic options/values are:

              syslog=<subsystems>  (see `-s' in slapd(8))
              syslog-level=<level> (see `-S' in slapd(8))
              syslog-user=<user>   (see `-l' in slapd(8))

only output a prettified form of the DN, suitable to be used in a check and beautification tool; incompatible with -N.


enable verbose mode.


To check a DN give the command:

	/usr/sbin/slapdn -f //etc/openldap/slapd.conf -v DN
