That last pastebin (http://pastebin.centos.org/8316/) was krb5_child.log 
from a succesful first-time login on centos.

See http://pastebin.centos.org/8321/ for a password migration and output 
of ldapsearch.

Output of ldapsearch *after* logging in to CentOS for the first time:
     krbPasswordExpiration: 20140310183603Z
     krbLastPwdChange: 20140310183603Z
     krbExtraData:: AAITBh5Tcm9vdC9hZG1pbkBBLUVTS1dBRFJBQVQuTkwA
     krbLastFailedAuth: 20140310185101Z
     krbLoginFailedCount: 1
