[SSSD-users] CentOS 6.2 Kerberos Authentication Issue

Hi guys, i'm facing some trouble when i do ssh to a CentOS 6.2 machine using AD authentication. I am using SSSD, with krb5.conf and sssd.conf, well configured (tested in other OS, like RHEL). The account information comes when i make id or getent passwd. Seems something with ssh and kerberos troubles. I have already set 777 permission on /tmp and disabled SElinux, like logs indicates permission issue, but didn't get sucess. Have tried an update but in vain too. The krb5.child log is: Can anyone help me? Thanks, Hugo Lima.
