For the last approx 3 years we've been syncing AD groups with our DC as a 'gateway' via LDAP credentials.
I've already checked the Systems Manager - Configure - General
Confirmed that status of the sync is showing as a green tick
However, whenever I go to Systems Manager - Configure - Owners - Sync - AD Groups, I get the following message in RED at the top of the page
Unable to sync -- Please verify your Active Directory settings in Systems Manager > Configure > General.
Our APN Push Cert is still in date, our VPP and DEP tokens are still in date.
The 'gateway' device is using agent version 302.
We need the AD Sync to work as some of our software settings are linked to AD Groups.
I'm not sure what else to do. Anyone have any ideas?
