</div>Ok... Stop right there. Seems to suddenly be a lot of people running<br>
into this problem all of a sudden. You're running on a combination of<br>
old kernel and old version of LXC that do not play nice together and,<br>
yes, that the early F20 kernel with the distro distributed version of<br>
LXC. We've been having an active discussion about this bug in several<br>
forums.<br>

Please note comments #6 & #7<br>

I've noticed that this issue should be fixed in v3.13-rc1<br>
<br>
As mentioned in commit<br>
<br>
<a href="http://o.cs.uvic.ca:20810/perl/cid.pl?cid=83fa6bbe4c4541ae748b550b4ec391f8a0acfe94" target="_blank">http://o.cs.uvic.ca:20810/perl/cid.pl?cid=83fa6bbe4c4541ae748b550b4ec391f8a0acfe94</a><br>
<br>
CONFIG_AUDIT_LOGINUID_IMMUTABLE=y was removed. Could you please retest it on the latest Fedora?<br>

Hi,<br>
I have tried with the latest upgrades of F20 and the problem has been fixed.<br>
Thank you very much for the support!<br>
<br>

<br>
So, you have 2 choices.<br>
<br>
1) Update your F20 system to the latest kernel. My development server<br>
is currently running 3.14.4-200.fc20.x86_64 from Fedora Updates.<br>
<br>
2) Go through the files in ${root_fs}/etc/pam.d and make the following<br>
changes:<br>
<br>
- session required pam_loginuid.so<br>
+ # session required pam_loginuid.so<br>
<br>
Either of those will enable you to log in once again. If you don't to<br>
either, there is no combination of user name or password that will work,<br>
due to the error being generated out of pam_loginuid.so.<br>

This is the smoking gun. This indicates precisely and exactly that you<br>
are running into the pam_loginuid.so conflict bug.<br>
