yppasswd crypt() failed errors when using passwd.adjunct

replaces broken yp-tools-2.12-adjunct.patch
Description of problem:
When using passwd.adjunct map, yppasswd command fails with "crypt() failed" error, since it tries to use the "##user" string as salt. There's a patch, yp-tools-2.12-adjunct.patch, that attempts to fix this, but it gets it wrong.
Version-Release number of selected component (if applicable):
yp-tools-2.14-5 in Fedora 23, but also yp-tools-2.14-3.el7 in RHEL 7, and possibly other Fedora versions.
Consistently fails when using passwd.adjunct.
Steps to Reproduce:
1. Set up passwd.adjunct map on NIS server
2. Run yppasswd command on NIS client (F23 or RHEL7)
3. Enter passwords when prompted
"crypt() failed" error in response to new passwords
Should accept password without checking against "##user" string, and generate correct salt before calling crypt()
yp-tools-2.12-adjunct-fix.patch (attached) fixes problem. Use it instead of broken yp-tools-2.12-adjunct.patch file in src.rpm.
This message is a reminder that Fedora 23 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 23. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as EOL if it remains open with a Fedora 'version'
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version.
Thank you for reporting this issue and we are sorry that we were not
able to fix it before Fedora 23 is end of life. If you would still like
to see this bug fixed and are able to reproduce it against a later version
of Fedora, you are encouraged change the 'version' to a later Fedora
version prior this bug is closed as described in the policy above.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
This bug still exists in RHEL7, and most likely in newer Fedora releases.
Thanks for the report. I pushed the patch into rawhide and F25.
