Check if a group exists in Active directory

Check if a group exists in Active directory

Note: To add or read properties from an Active Directory group you need to have special username and password like an Active Directory admin.

DirectoryEntry addGroup;

string folderPath = "LDAP://CN=" + folderName + ",";

folderPath += "OU=SharedFolder,OU=Groups,DC=aaaaaa,DC=com";

protected Boolean chkGroupExistence(DirectoryEntry addGroup)

    {

        // chk if the requested AD group is available and a proper AD Group object is formed.    

        bool groupExists = true;

        try

        {

            if (addGroup.SchemaClassName == "group")

            { groupExists = true; }

        }

        catch (Exception)

        {

            groupExists = false;

        }

        return groupExists;

    }
