It seems to be returning an error requiring ldaps over port 636. Is it possible to bypass this step?
We're currently running Thycotic Password Reset Server in a private VPC, so we're not worried about access from the outside world. I'm just trying to figure out how that platform is allowing the changes over 389 and PWM throws up a hard "nope!"...
I am not too familiar with samba when it is working like an AD domain and its configuration but maybe it also allows insecure password changes. You can setup ldaps on simple ad pretty easily though, https://aws.amazon.com/blogs/security/how-to-configure-an-ldaps-endpoint-for-simple-ad/
