Re: Current ideas on kerberos requirements for Samba4

This originally sent to Jerry by mistake.

I too do not wish to stoke any flames, but Jerry has made a point I
support (albeit not a kerberos one for which I apologise).

I don't work with any sites that use AD. I do inhabit mailing lists that
are heavily into mail systems. An increasingly common subject is how to
sensibly run serious MTAs as protection for MS Exchange server. This
requires the MTA to know about the users in the system and requires
seriously scalable access to the LDAP side of AD.  For big sites, the
problems are major in that lack of scalability can result in their email
system going down under a spammers' dictionary attack.
