If you use kerberos for authentication and you’ve recently moved to Fedora 14, you may encounter this error while requesting a ticket with
kinit: KDC has no support for encryption type while getting initial credentials
The bug report suggests the following workaround (which worked for me):
As a temporary workaround, systems which need to continue to use the weaker ciphers can be configured with “allow_weak_crypto = yes” in the [libdefaults] section of their respective /etc/krb5.conf files.
