What do you mean by "doesn't work"? In what context do you use %ldapctrl and
@tableau? What do you expect to happen, and what does happen?

In C you call this ldctl_value; I'm not sure why you call it "berval" here.

You should use \%ldapctrl here -- you need to take a reference to the hash,
otherwise the hash flattens into a list which get put into the array. (Just
as you need to take the address of the LDAPControl structure in C, rather
than putting the structure itself into the array -- though C does also have
arrays of structures, which Perl doesn't.)

Shouldn't this be:
strcpy(ldapctrl.ldctl_oid, "2.16.840.1.113730.3.4.2");
ldapctrl.ldctl_value.bv_len = strlen("123");
strcpy(ldapctrl.ldctl_value.bc_val, "123");
(possibly with two previous malloc()s for ldctl_oid and bc_val)?

The code where you use ldapctrl and/or tableau would help; also, the
definition of the LDAPControl C structure. I assume you want to interface to
some pre-written code, in which case you have to follow the conventions that
code expects. For example, if the code expects a C structure, you may have
to use pack() in Perl to simulate this.
