This looks like your problem. Apparently, the krb5_child application
doesn't have permission to write to your /tmp directory[1]. Check its
permissions (and for SELinux AVC denials).
[1] While creating the credential cache to store the retrieved TGT, we
do so in a temp file in /tmp using the mkstemp() system call.
