During upgrade of postfix, nscd did not work properly because some symbols are not available. I wonder what needs to be done to make nscd available earlier during 'zypper dup'. The %pre/%post scripts in postfix do not use it directly, but the used getent/useradd/... binaries may try to use it. The Requires(pre/post) in postfix.spec are apparently ok, except the incorrect conditional for getent. glibc was upgraded before postfix, so this is not the issue here.

Upgrade was blocked by various bugs in the last months, they got fixed only until very recently. Thats the reason for the huge jump forward.
