           Summary: pam_session_close called as user or not at all
           Product: Portable OpenSSH
           Version: -current
          Platform: All
               URL: http://marc.theaimsgroup.com/?l=openssh-unix-
                    dev&m=106458208520320
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: PAM support
        AssignedTo: openssh-bugs at mindrot.org
        ReportedBy: dtucker at zip.com.au


Reported by Dr. Carsten Benecke:
"I guess that the forked child process that calls the sshpam_cleanup() 
function is forked before the parent calls do_pam_session() (which sets 
sshpam_session_open to true)."

and Chris Jensen:
"But when I exit the session, pam_sm_close_session gets called, but it
only runs as the user that was logged in, so it doesn't have
permission to unmount the directory."

The PAM session modules are called in the forked child but the cleanup should be
done as root in the parent.  Will attach a patch shortly.
