Description of problem: When SSSD is configured to get the sudo entries, the sudo long listing option does not list the rule names.
If there are 100s of rules present, it is difficult to then name of the rule allowed/denied sudo commands.

Version-Release number of selected component (if applicable): sudo-1.8.6p3-7.el6


How reproducible: Always.


Steps to Reproduce:
1. Setup Client to use 'sss' for sudoers
2. execute sudo -ll 

Actual results: sudo -ll does not list the rule name(s).

Expected results: long listing includes the rule name.

Additional info: Example:
------------------------------
sudo_LDAP

# sudo -ll -U luser1
User luser1 may run the following commands on this host:

**LDAP Role: storage**
    RunAsUsers: ALL
    Commands:
    /bin/fdisk

**LDAP Role: passwd**
    RunAsUsers: ALL
    Commands:
    /usr/bin/passwd
[root@dhcp210-115 sssd]#

sudo_SSS

[root@dhcp210-115 sssd]# !vi
vi /etc/sudo-ldap.conf
[root@dhcp210-115 sssd]# vi /etc/nsswitch.conf
[root@dhcp210-115 sssd]# sudo -ll -U luser1
User luser1 may run the following commands on this host:
    RunAsUsers: ALL
    Commands:
    /bin/fdisk
    RunAsUsers: root
    Commands:
    /usr/bin/passwd
    RunAsUsers: ALL
    Commands:
    /bin/be_admkn
------------------------------

As you can see, when we use ldap, it lists the rule, and the rule name is
missing with sssd.
