Integration tests are broken

[jsumners]

While working on a test case for #923 I discovered that the latest Docker image is failing on:

node-ldapjs/test-integration/client/issues.test.js

Lines 12 to 41 in 1cc6a73

	tap.test('modifyDN with long name (issue #480)', t => {
	const longStr = 'a292979f2c86d513d48bbb9786b564b3c5228146e5ba46f404724e322544a7304a2b1049168803a5485e2d57a544c6a0d860af91330acb77e5907a9e601ad1227e80e0dc50abe963b47a004f2c90f570450d0e920d15436fdc771e3bdac0487a9735473ed3a79361d1778d7e53a7fb0e5f01f97a75ef05837d1d5496fc86968ff47fcb64'
	const targetDN = 'cn=Turanga Leela,ou=people,dc=planetexpress,dc=com'
	const client = ldapjs.createClient({ url: baseURL })
	client.bind('cn=admin,dc=planetexpress,dc=com', 'GoodNewsEveryone', bindHandler)
	function bindHandler (err) {
	t.error(err)
	client.modifyDN(
	targetDN,
	`cn=${longStr},ou=people,dc=planetexpress,dc=com`,
	modifyHandler
	)
	}
	function modifyHandler (err, res) {
	t.error(err)
	t.ok(res)
	t.equal(res.status, 0)
	client.modifyDN(
	`cn=${longStr},ou=people,dc=planetexpress,dc=com`,
	targetDN,
	(err) => {
	t.error(err)
	client.unbind(t.end)
	}
	)
	}
	})

The issue is that it hits: https://git.openldap.org/openldap/openldap/-/blob/2738a32de3a324fc56effd44c2fedaff1a359011/servers/slapd/back-mdb/modrdn.c#L442

We need to figure out how to get the MDB store to accept this, or figure out how to re-enable HDB.

The following script shows the error with the standard CLI tools:
