>From time to time on centos 6 sssd I got login problems like 'connection closed by *.*.*.*.', after a while then I login in again and the problem already disappeared. For the ssh login problem, I can see the following entries in /var/log/secure. 'Failed public key for ....' is the entry for the login problem. Any one has some ideas why this happens?
