Jenkins login issue
<p>Just setup jenkins on Ubuntu v16 laptop.</p>

<p>I have followed the installation steps from this <a href="https://wiki.jenkins-ci.org/display/JENKINS/Installing+Jenkins+on+Ubuntu" rel="noreferrer">page</a></p>

<p>After I setup, I fetched the setup password from <code>/var/logs/jenkins/jenkins.log</code> &amp; was able to setup the admin user/password. I made a note of the creds.</p>

<p>I was also able to access &amp; setup a simple <code>helloworld pipeline job</code>. </p>

<p>I stepped out and came back to my desk after about 20mins. The session has logged me out &amp; I am not able to log-in with the creds. I have tried removing jenkins &amp; setting it back. It still seems to retain the creds somewhere &amp; now I am getting to the login page with bad credentials error everytime.</p>

<pre><code>Invalid login information. Please try again. 
Try again
If you are a system administrator and suspect this to be a configuration problem, see the server console output for more details.
</code></pre>

<p>Need help figuring out what is happening. My logs have no useful information related to this error.</p>
