To use the Web Services for Microsoft Dynamics GP with TLS 1.2 you need to do two things:
- Upgrade to the Fall 2020 Release; you can’t just apply the hotfix to an October 2019 or earlier release, but have to use the full download media.
- Create an Active Directory Security Store.
Upgrading Dynamics GP is not a problem, but Active Directory isn’t my area of expertise. Fortunately, Microsoft have a set of instructions on the Dynamics GP Support and Services Blog which takes you through the creation of the security store.
Once the security store has been created, you need three pieces of information for the install of the web services:
- Name of the domain controller.
- Port 389.
- The partition string entered when creating the security store.
