On our cell there is NO entry in DNS, all is in the krb5.conf (for krb5)
and in the CellServDB (for OpenAFS DB Server).
It works fine for >7 years now.

And you should add all DB Servers to your CellServDB - maybe add it to
the official CellServDB list on openafs.org - to be included in every
new package of OpenAFS and you do not need to change the config of the
clients anymore.
