You are partly right.
However, IMHO building dovecot using standard openldap-devel on CentOS 5
means that, even though the final RPM works, it will use *ancient*
openldap v2.3 libraries.
If we manage to use custom openldap libaries (like those from LTB
Openldap builds) then Dovecot can be built against modern/current
Openldap v2.4 libraries. That may provide significant improvements to
the final RPM, in terms of LDAP usage.
In any case, I found the solution (based on the documentation:
http://wiki2.dovecot.org/CompilingSource); I added the following lines
(marked below with ++) in your spec file:
%build
export PATH=/usr/kerberos/bin:$PATH
#required for fdpass.c line 125,190: dereferencing type-punned
pointer will break strict-aliasing rules
++ export CPPFLAGS="${CPPFLAGS} -I/usr/local/openldap/include"
++ export LDFLAGS="${LDFLAGS} -L/usr/local/openldap/lib64"
export CFLAGS="$RPM_OPT_FLAGS -fno-strict-aliasing"
%configure
INSTALL_DATA="install -c -p -m644" \
--docdir=%{_docdir}/%{name}-%{version} \
--disable-static \
--disable-rpath \
--with-nss \
--with-shadow \
--with-pam \
--with-gssapi=plugin \
--with-ldap=plugin \
...
So, this produces a dovecot package based on Openldap 2.4
libraries(follows excerpt from the rpmbuild output):
...
Requires(interp): /bin/sh /bin/sh /bin/sh /bin/sh
Requires(rpmlib): rpmlib(CompressedFileNames) <= 3.0.4-1
rpmlib(PayloadFilesHavePrefix) <= 4.0-1
Requires(pre): /bin/sh shadow-utils
Requires(post): /bin/sh chkconfig shadow-utils
Requires(preun): /bin/sh chkconfig initscripts shadow-utils
Requires(postun): /bin/sh initscripts
Requires: /bin/bash /bin/sh config(dovecot) = 1:2.1.13-3.centme
initscripts ... libldap-2.4.so.2()(64bit) ...
...
It was initially using: libldap-2.3.so.0()(64bit)
