--> I think you have just discovered that sshd is no longer running
with priviledge separation. Have you compared the new sshd_config file
form the rpm to the old one ?
If priviledge separation is enabled, the main sshd daemon will fork a
process running under the UID of the user logging in and this process
will take care of the tunneling.
But the default with the new rpm is that priviledge separation is
disabled, i.d. the process handling the socket and taking care of the
tunneling is running as root.
This would explain your observation. Have you tried to switch on
priviledge separation in sshd_config, then restart the server and do
the same test ? What does it say now ?
