Description of problem:

when configuring to instruct sudo to gather sudo rules
over sssd, I get the folowing error message :

# sudo ls /etc/sssd

sudo: Unable to dlopen /usr/lib64/libsss_sudo.so: (null)
sudo: Unable to initialize SSS source. Is SSSD installed on your machine?


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

sssd-1.9.2-82.7.el6_4.x86_64

How reproducible:

Steps to Reproduce:
1. yum install sssd sudo sssd-client pam nss
2. echo "sudoers:   sss files" >> /etc/nsswitch.conf
3. add appropriate "sudo_provider" and "ldap_sudo_search_base" to sssd.conf
4. add "sudo" to "services =" in sssd.conf
5. echo "[sudo]" >> /etc/sssd/sssd.conf

Actual results:

sudo: Unable to dlopen /usr/lib64/libsss_sudo.so: (null)

Expected results:

grant access based on sudo rules found in sssd

Additional info:

To fix this bug, download and install libsss_sudo (from
rpmfind for example : tested with libsss_sudo-1.9.2-82.10).


Normally, libsss_sudo should be packaged within redhat
sudo package.
