I already did touch /.autorelabel and it relabeled all my system and this still happening. Is it a bug ?

SELinux is preventing /bin/login from 'read' accesses on the lnk_file .ecryptfs.

*****  Plugin catchall (100. confidence) suggests  ***************************

If you believe that login should be allowed read access on the .ecryptfs lnk_file 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 login /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
