<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Lucida Console"">I recently upgraded a box with a Spacewalk 2.6 instance from Oracle Linux 7.3 to Oracle Linux 7.4 and SELinux started complaining about a lot of stuff regarding java/tomcat. It
broke my ability to auth using Kerberos/PAM to the web interface. If I change to permissive mode via “setenforce 0” I can login like normal, no problems. Even after running the sealert commands to set local policies to in theory fix the problems, SELinux in
enforcing mode breaks my normal auth. <o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Lucida Console"">I’m seeing this stuff in the syslog, but even after applying the custom policies, with SELinux enforcing I still can’t login. Anyone else noticing this?<o:p></o:p></span></p>
