Just a note that there is a similar Bug 1722311, but it is for RHEL 7.6, so it is not duplicate. I had to downgrade back to freerdp 1.0.2 to get back this functionality to Server 2012. Please continue to assist upstream in fixing this. In August, 2016, I built a freerdp versioned 2.0.0-5.git.b02943a that works fine in RHEL6, if that helps at all. I'll bring up a bug mentioned upstream. Fixing the issue where the Linux clients don't trigger the smart card manager service to start in Windows would be awesome. We currently run a scheduled task to restart it every minute. If it's related to this bug, please fix both! This regression was unpleasant to deal with. The upgrade was also not mentioned in the 7.7 release notes. This has my customer vote!

I'm sorry about it, but we are working on it. It is confirmed that https://github.com/FreeRDP/FreeRDP/pull/5499 fixes the SCARD_INSUFFICIENT_BUFFER errors and restore the functionality, but still, SCardListReadersW errors are reported (https://github.com/FreeRDP/FreeRDP/issues/5791), although it seemingly doesn't affect functionality. We are trying to figure out why. > In August, 2016, I built a freerdp versioned 2.0.0-5.git.b02943a that works > fine in RHEL6, if that helps at all. > > I'll bring up a bug mentioned upstream.

If it's related to this bug, please fix both! Also, we are currently trying to fix the autostarting of smartcard service, see https://github.com/FreeRDP/FreeRDP/pull/5793. However, we don't have a proper environment for testing right now and rely on feedback. If you are willing to help, support team can you provide testing builds, or alternatively you can try building freerdp master yourself. Thanks for understanding. The test build I got from the support case fixed the main issue that smart card auth no longer worked. I might be able to check on the smart card redirect/service autostart thing given test builds. Looks like the upstream jenkins has RPM builds https://ci.freerdp.com/job/freerdp-nightly-rpm-mock/ but they probably won't install in RHEL7.

I haven't tested those builds on RHEL 7, but we have already feedback for https://github.com/FreeRDP/FreeRDP/pull/5793 from other people and it causes some undocumented behavior for them, unfortunately. It is confirmed that https://github.com/FreeRDP/FreeRDP/pull/5499 fixes SCARD_INSUFFICIENT_BUFFER error, so I would suggest using this report to fix only this issue as it caused regression after rebasing to 2.0-rc4. The problem with autostarting smartcard service on the server is not a regression as it never worked with freerdp and it is pretty unclear what needs to be done to fix it. So I would suggest using Bug 1722311 for it to not block fixing the SCARD_INSUFFICIENT_BUFFER errors. Fortunately, the server-side workaround exists. This bug is about the regression. I understand the lack of autostart is a separate issue. I would appreciate this bugfix getting into an errata. |
