Unfortunately, currently you cannot access Logging from the Adaxes Web Interface. This feature is in our TODO list.
As a workaround, you may access log records using a PowerShell script. See the section called Get Adaxes Log Records Using Script in the View AD Operations Performed via Adaxes Tutorial and also the Accessing Log Records article in the Adaxes SDK.
Also, you cannot allow a user who is not an Adaxes administrator to view ALL approval requests. Users who are not administrators can view only their Approval Requests (i.e. the requests either initiated by them or assigned to them). As a workaround, you may create a Scheduled Task that will add people from the helpdesk staff to the list of Approvers of an Approval Request if the Approval Request remains pending for X days/hours.
