Description of problem:
1. Start Cockpit
2. Attempt to login using an Admin account
3. Login is denied due to a SeLinux denial

Cockpit as a service should by default have access to these privilages
SELinux is preventing /usr/libexec/cockpit-session from using the 'sys_resource' capabilities.

*****  Plugin sys_resource (91.4 confidence) suggests   **********************

If you do not want processes to require capabilities to use up all the system resources on your system;
Then you need to diagnose why your system is running out of system resources and fix the problem.  

According to /usr/include/linux/capability.h, sys_resource is required to:

/* Override resource limits. Set resource limits. */
/* Override quota limits. */
/* Override reserved space on ext2 filesystem */
/* Modify data journaling mode on ext3 filesystem (uses journaling
   resources) */
/* NOTE: ext2 honors fsuid when checking for resource overrides, so
   you can override using fsuid too */
/* Override size restrictions on IPC message queues */
/* Allow more than 64hz interrupts from the real-time clock */
/* Override max number of consoles on console allocation */
/* Override max number of keymaps */
/* Override resource limits. Set resource limits. */
/* Override quota limits. */
/* Override reserved space on ext2 filesystem */
/* Modify data journaling mode on ext3 filesystem (uses journaling
   resources) */
/* NOTE: ext2 honors fsuid when checking for resource overrides, so
   you can override using fsuid too */
/* Override size restrictions on IPC message queues */
/* Allow more than 64hz interrupts from the real-time clock */
/* Override max number of consoles on console allocation */
/* Override max number of keymaps */
/* Override resource limits. Set resource limits. */
/* Override quota limits. */
/* Override reserved space on ext2 filesystem */
/* Modify data journaling mode on ext3 filesystem (uses journaling
   resources) */
/* NOTE: ext2 honors fsuid when checking for resource overrides, so
   you can override using fsuid too */
/* Override size restrictions on IPC message queues */
/* Allow more than 64hz interrupts from the real-time clock */
/* Override max number of consoles on console allocation */
/* Override max number of keymaps */

Do
fix the cause of the SYS_RESOURCE on your system.

*****  Plugin catchall (9.59 confidence) suggests   **************************

If you believe that cockpit-session should have the sys_resource capability by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# grep cockpit-session /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
