slapd-config is a manual page, not an executable.

	man slapd-config
		Describes the LDAP/LDIF configuration method

	man slapd.conf
		Describes the flat text-file configuration method

Both methods configure the same things, so those pages are quite
similar. The keywords / attribute names are different though, so
make sure you read the right one for the method you are using.

Use 'ps ax | grep slap' to see whether there are any command-line options
applied to the slapd process. If there are, look them up in 'man slapd'
taking particular note of the -f and -F options. If those options are not
present then the daemon will use the default config database (see slapd-config
above) or, failing that, will use the default config file (see slapd.conf
above).

Each of those manual pages starts with a note of exactly where the
default database or config file will be found on your system.

'lsof -p <slapd PID>' perhaps :-)

Modules can be backends or overlays. I cannot think of a single command
that finds all loaded slapd modules. You can find what backends and
overlays are available/active by browsing under cn=monitor. Similarly
you could search under cn=config to find what the config says *should*
be loaded.
