[Bug 362427] Re: Public key ssh auth doesn't work with my Encrypted Home Directory

[bulldozer2003]

If you've implementing Dustin's workaround, you may run into a delay
when logging in, and an Xauthority error. This is caused by xauth being
unable to write to your home directory before the encrypted directory is
mounted.

Here is my workaround. Using the ~/.ssh/rc file, the xauth parameters
are written to a temp file, then read into a variable before your
encrypted $HOME is mounted, then passed to xauth.

 put the following files in your UN-encrypted home directory.

~$ cat .ssh/rc 
#!/bin/bash
if read proto cookie && [ -n "$DISPLAY" ]; then
  if [ $(echo $DISPLAY | cut -c1-10) = 'localhost:' ]; then
    # X11UseLocalhost=yes
    echo add unix:$(echo $DISPLAY | cut -c11-) $proto $cookie > ~/.ssh/xauth_temp
  else
    # X11UseLocalhost=no
    echo add $DISPLAY $proto $cookie > ~/.ssh/xauth_temp
  fi
fi

~$ cat .bash_login 
#!/bin/bash
if test -e $HOME/.ecryptfs/auto-mount; then
  XAUTH=$(cat ~/.ssh/xauth_temp)
  mount | grep "$HOME type ecryptfs"
  if test $? != 0; then
    ecryptfs-mount-private
    cd $HOME
    source ~/.bashrc
  fi
  echo $XAUTH | xauth -q -
fi

Hope this helps someone!

The original .bash_login script comes from:
