[Evolution] Something Broke with exchange/ldap

[David Ronis <ronis ronispc chem mcgill ca>]

I recently upgraded evolution from version 2.4.1 to version 2.6.1, first
using the freerock-gnome for slackware packages, and then by building my
own from scratch (specifically, I built 

                            evolution-2.6.1
                      evolution-data-server-1.6.1
                        evolution-exchange-2.6.1

                                  and

                            openldap-2.3.20

                                   or

                            openldap-2.3.23

In all cases I applied the openldap-ntlm.diff patch.  Everything works
except for exchange and ldap, where I either get authentication errors
or things crash.  I've checked with my office's exchange folks and they
see the login attempts in their logs.  They tell me that nothing has
changed with their exchange settup in months.  Also, nothing has changed
with my accounts, and indeed, if I go to another machine running 2.4.1,
things work as before.

My suspicion is that either freerock-gnome or I have misconfigured some
package.

Here's what I pass to configure:

for evolution-2.6.1:

 ./configure --prefix=/usr --with-openldap=yes
--with-krb4-libs=/usr/local/lib --with-krb5-libs=/opt/heimdal/lib
--with-krb4-includes=/usr/local/include/kerberosIV
--with-krb5-includes=/opt/heimdal/include --with-krb4=/usr/local
--with-krb5=/opt/heimdal

for evolution-data-server-1.6.1:

 ./configure --prefix=/usr --with-openldap=yes
--with-krb4-libs=/usr/local/lib --with-krb5-libs=/opt/heimdal/lib
--with-kr4-includes=/usr/local/include/kerberosIV
--with-krb5-includes=/opt/heimdal/include --with-krb4=/usr/local
--with-krb5=/opt/heimdal

for evolution-exchange-2.6.1:

 ./configure --prefix=/usr --with-openldap=yes

and finally, for openldap:

./configure --prefix=/usr --with-tls --disable-static --disable-debug
--enable-tls --enable-ldap --enable-passwd

Any help would be appreciated.  I've also reported this as a bug to
bugzilla.gnome.org, bug number 342593, but not much seems to have
happened.

Thanks
