Error 1655 when loading dll compiled with VC-LTL5 under lsass in protected mode

Thanks for this contribution to the community.

I'm opening this issue, but this is more a "for your information" rather than a real issue to fix.

I'm writing plugins for LSASS (such as password filter and authentication package). I'm writing them for production and it needs to be signed by Microsoft in order to load. I tried your plugin and I got this error:

The error 1655 is undocumented but seems related to dynamic code being denied. Indeed, lsass is a very sensitive process and is heavily protected.

When I remove the package VC-LTL5, it loads again correctly.

I'm not expecting any solution, this is just to share information in case a similar 1655 error popups. You can close this issue immediately.
