That's a direct lookup of an entry by its name (DN).  LDAP implements
that as a a search with scope=base, which only examines the named DN.

To search for employee number when that is not part of the entry name,
use search filter "(employeeNumber=1031275942)"
or maybe "(&(employeeNumber=1031275942)(objectClass=lifeUser))".

With search scope subtree (sometimes called sub) you can use search base
"dc=example,dc=co,dc=za" or "ou=somewhere,dc=example,dc=co,dc=za".  With
search scope onelevel (also called singleLevel or one) you can only use
the latter search base.

Also read up on LDAP basics.  The difference between DN and filter is
_very_ basic.
