Verify your service account and Base DN
Use a tool such as the Active Directory Explorer from Microsoft to connect with the same service account you have configured the AD Usersource with.
Once connected, navigate to one of your users and note the "path." Verify that the path shown contains the same path you have configured the AD Usersource's "Base DN" option. For example,
CN=jdoe,OU=Members,OU=Test,DC=example,DC=com, then your Base DN should be set as
Verify your test user
Once you have selected a user, a list of their attributes will be displayed in the right pane. Find the "userPrincipalName" and "sAMAccountName" and verify that these are the usernames you are trying when testing the usersource. The AD Usersource is able to connect using either of these strings, make sure to try both.
Verify your test user credentials
Use a tool like Auth to confirm the user credentials and domain are correct.
Auth.exe is a command-line tool you should run from a network computer. You pass it three parameters for the domain to authenticate against, the user and the password. For example:
Auth.exe /d:mydomain /u:"email@example.com" /p:"password"
Make sure that the required ports are opened in any firewalls between the Deskpro helpdesk and your Active Directory server.
The main port you are likely to need to open is 389 or 636 if you are using SSL.
Note that Active Directory can use various different ports depending on how it is configured: here is a full list.
