I do sympathize with their plight. Core LDAP services are not things you
want to be forcing your customers to rebuild completely every two or three
years. How long did it take Stanford to turn off kerberos 4?
At least this switch can be staged easily.

There isn't any symbol pollution or anything, is there? Just risks if you
actually try to *use* kerberos calls in a multithreaded app?
I ask because RedHat links the world with MIT kerberos -- including
OpenSSL. As long as I don't configure SASL/GSSAPI, I don't have to mess
with recompiling a private copy of OpenSSL too, do I? RHEL 3 includes
openssl 0.9.7a plus backported security patches.
We still have application needs for simple binds and userPassword in the
directory, so kerberos would just be a singe-login convenience for myself,
mainly. Our kerberos servers are Windows boxes, so we've already lost the
"separate identification and authorization data from authentication tokens"

I have, thanks. I used to work in Pine Hall, so I've been cribbing Jeff and
Bob and successors for years. :-)
OK, so my only remaining unanswered question is how much I need to worry
about how well the new Native Poxix Threads Library stuff in RHEL 3 plays
with OpenLDAP. I guess nobody knows because the big sites just don't run on
I've considered switching to Solaris/Intel or even SPARC -- the Intel
price/performance advantage is much smaller than it used to be -- but
as a small school, I feel a need to stick with an OS my student sysadmins
can deal with in an emergency.
