  <summary>xdm: don't ignore an already existing ssh-agent when starting an X session</summary>
  <description>This update fixes the following issue with xdm:
- bnc#812783: During the start of an X session xdm always started an ssh-agent even if there was already running a working instance (e.g. started from pam_ssh) rendering the existing agent which might already have added keys unusable.</description>
