I'm getting this error in SolidCP 1.4.7 in a AD environment. It just started happening to 1 server out of a dozen.

ERROR: 'Windows Server 2016' GetGroupNtfsPermissions
System.ArgumentNullException: Value cannot be null.
Parameter name: sddlForm
at System.Security.Principal.SecurityIdentifier..ctor(String sddlForm)
at SolidCP.Providers.Utils.SecurityUtils.GetGroupNtfsPermissions(String path, UserPermission[] users, RemoteServerSettings serverSettings, String usersOU, String groupsOU)
at SolidCP.Providers.OS.Windows2003.GetGroupNtfsPermissions(String path, UserPermission[] users, String usersOU)
at SolidCP.Server.OperatingSystem.GetGroupNtfsPermissions(String path, UserPermission[] users, String usersOU)

I have confirmed the user on the SolidCP app pool has the correct rights and can not find any other issues. Any help would be appreciated.

Hello,

Can you confirm the user is a member of the Web users group as listed in the IIS provider settings? By default this is SolidCP_IUSRS.

Regards,

Trevor

Did anyone ever figure out what causes this?
Its occurring on one of my servers also.
