[Test] Increase LDAP connection timeout (#87208) (#88119)

Increased LDAP connection timeout to 10s to avoid test failures.

By default, LDAP and Active Directory's timeout was set to 5s.
This seems not to be enough when running integration tests on CI servers
that use Samba fixture.

Closes #86958
