Description of problem:

realm join fails with

 * Couldn't find file: /usr/bin/net
 * Required files: /usr/sbin/oddjobd, /usr/libexec/oddjob/mkhomedir, /usr/sbin/sssd, /usr/bin/net
 * Resolving required packages
 ! Necessary packages are not installed: oddjob, oddjob-mkhomedir, sssd, samba-common
realm: Couldn't join realm: Necessary packages are not installed: oddjob, oddjob-mkhomedir, sssd, samba-common

even if samba-common is installed.

Version-Release number of selected component (if applicable):

realmd-0.16.1-5.el7.x86_64

How reproducible:

Deterministic.

Steps to Reproduce:
1. yum install -y realmd oddjob oddjob-mkhomedir sssd samba-common
2. realm join -v addomain.test

Actual results:

 * Couldn't find file: /usr/bin/net
 * Required files: /usr/sbin/oddjobd, /usr/libexec/oddjob/mkhomedir, /usr/sbin/sssd, /usr/bin/net
 * Resolving required packages
 ! Necessary packages are not installed: oddjob, oddjob-mkhomedir, sssd, samba-common
realm: Couldn't join realm: Necessary packages are not installed: oddjob, oddjob-mkhomedir, sssd, samba-common

Expected results:

 * Couldn't find file: /usr/bin/net
 * Required files: /usr/sbin/oddjobd, /usr/libexec/oddjob/mkhomedir, /usr/sbin/sssd, /usr/bin/net
 * Resolving required packages
 ! Necessary packages are not installed: oddjob, oddjob-mkhomedir, sssd, samba-common
realm: Couldn't join realm: Necessary packages are not installed: oddjob, oddjob-mkhomedir, sssd, samba-common-tools

Additional info:

The /usr/bin/net is provided by samba-common-tools in RHEL 7.2.

Also note bug 1271608 which might provide cure if samba-common is fixed to require samba-common-tools but still, the list of packages should not be misleading.
