Bug Description

[IMPACT]

 * NIS authentication doesn't work.

[TESTCASE]

 * With postfix installed do:

$ postconf -m | grep nis

If that produces no output, you've reproduced the bug.

* Install the updated package and repeat. This time is should look like:

$ postconf -m | grep nis
nis

[Regression Potential]

 * Nil. It's just re-enabling a build flag for functionality that was previously dropped.

[Original Bug]

on a (freshly installed) system with nis authentication, postfix is no longer able to read aliases from the nis table mail.aliases.
in 10.04 it worked

symptoms are:
- errors in /var/log/mail.log:
warning: nis:mail.aliases is unavailable. unsupported dictionary type: nis
- and mail is not forwarded

Obviously some build switch was changed between 10.04 and 12.04.
In 10.04:
$ postconf -m | grep nis
nis

In 12.04 the output is empty.

But still in 12.04 the postfix.postinst skript looks for nis and creates an appropriate mail.cf entry for lookup in nis:mail.aliases

$ lsb_release -rd
Description: Ubuntu 12.04.1 LTS
Release: 12.04

$ apt-cache policy postfix
postfix:
  Installiert: 2.9.3-2~12.04.3

Yes. It was a build argument change. I found where it was done and I'm checking to verify if there was a reason for it.

Dropping it was inadvertent. I've uploaded a fix for both 12.04 and 12.10 which will be available for testing once the uploads are reviewed by the stable release updates team.

on the system where I had the problem I did this to verify the fix
- removed workarounds in main.cf
- sent emails and verified that they trigger the error and remain in the queue
- installed 2.9.3-2~12.04.4
-> bug is gone, mail works normally
