yum (dnf) list updates

Updating Subscription Management repositories.
Unable to read consumer identity

This system is not registered with an entitlement server. You can use subscription-manager to register.

Fix:

1. vi /etc/dnf/plugins/subscription-manager.conf

Change enabled to 0

[main]
enabled=0

Option 2.

Register system with a Satellite server.

Active log file changed? No way!

After verifying file permissions, still unable to login without entering passsord. Found issue where SELINUX was keeping the SSH service from reading the authorized_keys file. Issue encountered on a Red Hat 6 server.

Fix:
$ restorecon -R -v /home/user/.ssh
restorecon reset /home/user/.ssh context unconfined_u:object_r:home_root_t:s0->unconfined_u:object_r:ssh_home_t:s0
restorecon reset /home/user/.ssh/known_hosts context unconfined_u:object_r:home_root_t:s0->unconfined_u:object_r:ssh_home_t:s0
restorecon reset /home/user/.ssh/id_dsa context unconfined_u:object_r:home_root_t:s0->unconfined_u:object_r:ssh_home_t:s0
restorecon reset /home/user/.ssh/id_dsa.pub context unconfined_u:object_r:home_root_t:s0->unconfined_u:object_r:ssh_home_t:s0
restorecon reset /home/user/.ssh/authorized_keys context unconfined_u:object_r:home_root_t:s0->unconfined_u:object_r:ssh_home_t:s0

Passwordless login now works:
