Description of problem:
error messages logged by sssd when sssd.conf is invalid are confusing

Version-Release number of selected component (if applicable):
libsss_autofs-1.9.2-7.el6.x86_64
sssd-1.9.2-7.el6.x86_64
libsss_sudo-1.9.2-7.el6.x86_64
libsss_idmap-1.9.2-7.el6.x86_64
sssd-client-1.9.2-7.el6.x86_64

How reproducible:
always

Steps to Reproduce:

echo Invalid permissions
> /etc/sssd/sssd.conf
chmod 644 /etc/sssd/sssd.conf
sssd -i

echo Empty file
chmod 600 /etc/sssd/sssd.conf
sssd -i

echo Invalid configuration
cat <<<"
[domain/default]
[sssd]
services = nss, pam
config_file_version = 2
domains = 
" > /etc/sssd/sssd.conf
sssd -i

Actual results:
Invalid permissions
(Thu Nov  8 14:04:57:043303 2012) [sssd] [main] (0x0020): Cannot read configuration file /etc/sssd/sssd.conf
Empty file
(Thu Nov  8 14:04:57:048903 2012) [sssd] [main] (0x0020): Error loading configuration database: [22]: Invalid argument
Invalid configuration
(Thu Nov  8 14:04:57:247281 2012) [sssd] [main] (0x0020): Error loading configuration database: [2]: No such file or directory

Expected results:
something like this:

Invalid permissions
(Thu Nov  8 14:04:57:043303 2012) [sssd] [main] (0x0020): Configuration file /etc/sssd/sssd.conf mode bits too permissive
Empty file
(Thu Nov  8 14:04:57:048903 2012) [sssd] [main] (0x0020): Error loading configuration file /etc/sssd/sssd.conf: configuration invalid
Invalid configuration
(Thu Nov  8 14:04:57:247281 2012) [sssd] [main] (0x0020): Error loading configuration file /etc/sssd/sssd.conf: configuration invalid 

Additional info:

I understand that sssd produces additional, more meaningful error messages with
elevated debug level. However, the summary messages are very confusing and
should be fixed. Plus, the class of configuration error messages could be
changed to match the default debug level.
