Hi,
these patches depend on Sumit's "[PATCHES] ldap_child, krb5_child: copy
keytab and FAST ccache into memory".
When applied, the FAST ccache is created as the SSSD so that no Kerberos
networking code runs as the root user. In order to do that, the
krb5_child receives the SSSD user IDs as parameters.
I also have tests for the other functions in the child_common.c module
but I will send them separately to speed up the review.
