        <!--Skip Microsoft logs and so log only own logs-->

                writeTo="blackhole"

        <!--App logs-->
        <logger name="*"
                minlevel="Debug"
                writeTo="wrapper_loop_app" />

    </rules>
</nlog>

I want to update the password with a BackgroundTask Service to log in a network drive:

UpdateNasPasswordResponse result = await _settings.UrlGda[0]
    .Replace("{AppId}", _settings.AppId)
    .Replace("{Safe}", _settings.CoffreFort)
    .Replace("{Object}", _settings.Objet).GetJsonAsync<UpdateNasPasswordResponse>();

LoggingConfiguration config = LogManager.Configuration;
config.Variables["password"] = HttpUtility.HtmlEncode(result.Password);
LogManager.KeepVariablesOnReload = true;
LogManager.ReconfigExistingLoggers(true);

I try using variable, gdc and getting directly the target:

UpdateNasPasswordResponse result = await _settings.UrlGda[0]
    .Replace("{AppId}", _settings.AppId)
    .Replace("{Safe}", _settings.CoffreFort)
    .Replace("{Object}", _settings.Objet).GetJsonAsync<UpdateNasPasswordResponse>();

LoggingConfiguration config = LogManager.Configuration;
ImpersonatingTargetWrapper target = config.FindTargetByName<ImpersonatingTargetWrapper>(InfrastructureConsts.Nlog.WrapperTarget);
target.Password = HttpUtility.HtmlEncode(result.Password);
LogManager.ReconfigExistingLoggers(true);

I can log the new password in another class but the targets inside the ImpersonatingWrapper didn't seems to be able to log in our NAS.

If I put the password directly inside the nlog.config everything works fine.

Created pull-request #5 to add Layout support for UserName / Domain / Password for ImpersonatingWrapper.

[snakefoot]

NLog.WindowsIdentity ver. 5.3 has been released with Layout-support for UserName + Domain + Password:

• https://www.nuget.org/packages/NLog.WindowsIdentity/5.3.0

Thus allowing password="${var:password}"

Thanks a lot!
