On Fedora 21 we have /etc/request-key.d/cifs.upcall.conf and
/etc/request-key.d/cifs.idmap.conf to allow kernel to properly fetch
Kerberos keys and map IDs of CIFS identities. These configurations are
part of cifs-utils package which also supplies mount.cifs.



I have no /etc/request-key.d/cifs.upcall.conf on my F21. Is it suppose to
be there?
No, it was my fault, forgetting the actual name -- it is
cifs.spnego.conf that you have listed below:

This is what I have:

[root@ipaserver etc]# cat request-key.conf

[root@ipaserver etc]# cat request-key.d/cifs.spnego.conf
create  cifs.spnego    * * /usr/sbin/cifs.upcall %k
So if you have all these configs right, can you add --verbose to
mount.cifs arguments _before_ -o options?

mount -t cifs //ipaserver.MY.LAN/TheShare --verbose -o sec=krb5

and you can enable debugging before mounting in /proc/fs/cifs/, see
