I do agree there must be something else which broke the getpw call or the libc somehow. On another machine I also have compat for nsswitch.conf and it worked.
Also on my setup the Perl "getpwuid/getpwnam" functions were still working correctly despite the ntpd's call failing. I do not have a clear track about other packages which were upgraded and may have caused the failure, it can virtually be anywhere in the system. My libc6 is also 2.19-19, but there have been ways too many package upgrades for me to easily identify things step by step. -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
