One of my client have this issue where we can't create password longer than 16 chars. I just found this out because we switched to using long passwords for all our client domain admins. I have been unable to find any information on web searches other than Azure having this same limit at one point. I don't see the server connected to Azure, but was wondering if it some how propagated to the server and how we can remove that cap.
I checked the domain level and it was on 2003, so I raised it to 2012R2. Restarted and no difference. Any help would be great, Thanks.
