Just a heads up. KerberosV was recently removed from the Base install in Current. Some userland apps, ie mutt, use KerberosV for ssl encryption and will crash. The Plan is to come up with a KerberosV package.
kerberosV has been removed. The login methods "krb5" and "krb5-or-pwd" are not supported anymore and should be removed from login.conf(5). Many dependencies and packages have to be updated. The libraries, headers and other related files should be removed from the system.
long list of files to remove
Remaining users of kerberosV should download and install the software manually or use the kerberos packages when they become available.
