Description of problem:
No idea. Message just popped up randomly soon after rebooting while I was working on something.
Not sure if this is a policy problem or a problem with sssd, but figure I'll report it anyway...
-------------------[snip]------------------
SELinux is preventing /usr/libexec/sssd/sssd_be from 'module_request' accesses on the system .

*****  Plugin catchall_boolean (89.3 confidence) suggests   ******************

If you want to allow all domains to have the kernel load modules
Then you must tell SELinux about this by enabling the 'domain_kernel_load_modules' boolean.
You can read 'kernel_selinux' man page for more details.
Do
setsebool -P domain_kernel_load_modules 1

*****  Plugin catchall (11.6 confidence) suggests   **************************

If you believe that sssd_be should be allowed module_request access on the  system 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 sssd_be /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
