Sorry for the poorly formed summary. If you are using sssd for account information a few Steam games such as Civ 5 and Borderlands 2 segfault on launch due to there not being a 32-bit version of libnss_sss.so.2. Would it be possible to get a multiarch build of sssd? Attached is an strace of Borderlands 2, I can also provide one of Civ 5 if requested. This is similar to the bug posted on Valve's bugtracker here: https://github.com/ValveSoftware/steam-for-linux/issues/3031
