v2023.2.6.2 errors with 0x0000000D when using Duo Network Gateway

Hopefully this doesn't turn in to finger pointing, but RDM v2023.2.5.1 works fine with MacOS 13.4.1(c) and v2023.2.6.2 gives me 0x0000000D when connecting through the RDP proxy that Duo Network Gateway (DNG) provides. Direct RDP connections seem to work fine.

the DNG logs show this

Hello

We're tracking a regression on the 2023.6.x release with certain RDP authentication scenarios. Could you check if it's the same issue by setting "Authentication > SSPI > SSPI Module" to "System" on one of the affected entries and let me know if it corrects the issue?

I apologize for the inconvenience. Please let me know if you have a question or something isn't clear

Thanks and kind regards,

Richard Markievicz

bingo. Same issue. Setting "Authentication > SSPI > SSPI Module" to "System" allows it to connect.

Hello again

Thanks for confirmation. I apologize for the regression and the inconvenience caused. We will fix this as soon as possible.

In the meantime, the possible workarounds are:

  • Temporarily revert to the prior version (2023.2.5.1, download here)
  • Modify the affected entr(ies) to use the "System" SSPI module


Once again, I do apologize and assure you we're working hard to correct that.

Please don't hesitate if you have other questions or concerns

Kind regards,

Richard Markievicz

Thanks for the quick response. That makes up for the inconvenience. I've reverted back to 2023.2.5.1 for now.
