    Hi ,


    I donot want to add roles. I have to give user additional rights to manage Group in AD. I found the code for that, but dont know what name to add for "User_Name". Is it the dintinguished name or logon name.

    DirectoryEntry directoryEntry = new DirectoryEntry("LDAP://path for Group");

    ActiveDirectorySecurity adSecurity = directoryEntry.ObjectSecurity;

    string sd = adSecurity.GetSecurityDescriptorSddlForm(AccessControlSections.All);

    IdentityReference newidentity = new System.Security.Principal.NTAccount("User_Name");

    ActiveDirectoryAccessRule newAccessRule = new ActiveDirectoryAccessRule(newidentity, ActiveDirectoryRights.WriteOwner, AccessControlType.Allow);

    Hi nix

    You could refer the case about assigning rights to the user group for particular OU in Active directory using C# below,


    Moreover,  it's necessary for you to learn the usage of AddAccessRule method in ActiveDirectorySecurity Class,


    Kind regards
