Does anyone have a solution or method for using Solarwinds to monitor changes to local group memberships?
Dell AD/Server Security Audit product does it beautifully (formerly Quest).
Using SolarWinds SAM you may need to collect the events and alert on those which is ugly. Or buy their SIEM/LEM product and see if they have it built in events.
orioncrack is correct. SAM is not a configuration change management solution. You could achieve something close by enabling Active Directory auditing and utilizing SAM's Windows Event Log Monitor to notify you of changes you're interested in. The other option would be to leverage LEM (Log & Event Manager) which is far better suited for security and auditing tasks, such as these.
