A server error has occurred - Profile Manager Server 5 - kerb5.conf
When browsing Profile Manager via the web browser, I frequently get the dreaded "a server error has occurred" and SOMETIMES a "JASON < " error.
PM was fine on server 4, but server 5 has broken stuff.
When the error message appears, I get the following in my logs :
09/12/2015 10:03:00.556 sandboxd[132]: ([8094]) rpcsvchost(8094) deny file-read-data /private/etc/krb5.conf
(opening the kerb.conf file shows just the following )
[libdefaults]

Any thoughts would be most appreciated.
