VRDP external auth library path lookup fails (regression) => Fixed in SVN

[Michael]

I have a VM server running multiple guests of different OSes. The machine was running VirtualBox 3.2.12 for the past month with no issues. I used VRDP with authentication set to external and used my host user to login successfully.

After upgrading to 4.0.0 I can no longer use external auth. I must set it to "none" to be able to connect to the RDP session.

The Extension Pack is installed. The Machine Log shows that VirtualBox cannot find the VRDPAuth.so library. I attempted to place a symlink to it in /usr/lib/virtualbox but then it is linked to VBoxRT.so. Creating a symlink for VBoxRX.so in /usr/lib64 still fails somewhere else when I try to connect with RDP.

Host: Fedora 13 x86_64 fully up-to-date

I have a similar bug under Windows. VRDPAuth is trying to be loaded instead of VBoxAuth by vboxwebsrv. It causes an issue with phpvirtualbox-4-2.

My workaround has been to duplicate VBoxAuth an rename it to VRDPAuth.

Still broken in 4.0.2. Same problem.

Still broken in 4.0.4. Same problem. Workaround still works. Thanks!

[Frank Mehnert]

Thanks for the report. That problem will be fixed in the next maintenance release.

I can confirm this is fixed. Thanks Frank, etc.!
