Hi Daniel,
I have checked the file_contexts file
#grep :login_exec_t contexts/files/file_contexts
/bin/login -- system_u:object_r:login_exec_t:s0
/bin/login\.shadow -- system_u:object_r:login_exec_t:s0
/bin/login\.tinylogin -- system_u:object_r:login_exec_t:s0
/usr/kerberos/sbin/login\.krb5 -- system_u:object_r:login_exec_t:s0
Now If I run with permissive mode. I Could see below login programs are running
(Here I gave unconfined_r as role and s0 as range)
1109 root 3540 S /bin/login --
1111 root 0 SW [kauditd]
1113 root 3020 S -sh
But when I run with enforcing mode I get same error

Would you like to enter a security context? [N] Y
