With latest ldapts veresion we are checking isConnected wrong

[stalkerg]

This trace:

TypeError: Cannot read properties of undefined (reading 'isConnected')
    at authenticateWithUser (/node_modules/ldap-authentication/index.js:242:24)

We do now:

try {
    ldapUserClient = await _ldapBind(userDn, userPassword, starttls, ldapOpts)
  } catch (error) {
    if (ldapUserClient.isConnected) {
      await ldapUserClient.unbind()
    }
    throw error
  }

But if we will catch an exception here, the ldapUserClient will be undefined.

should be fixed in the latest release v3.3.3
