I'm trying to configure the openldap with slurpd.
I've tryed with both 2.0.11 / 2.0.15, but I got this error every time:

checking for _beginthread... no

configure: error: could not link with POSIX Threads

I've just update my Red Hat 7.0 with 
glibc-common-2.2-12
glibc-profile-2.2-12
glibc-2.2-12
glibc-devel-2.2-12
cpp-2.96-85

I've tryed manu configure options, but with the same error.

I read also this on a manual:
CC="gcc" CFLAGS="-O3 -march=i686 -mcpu=i686 -funroll-loops -fomit-frame-pointer
-D_REENTRANT -fPIC" ./configure --prefix=/usr --libexecdir=/usr/sbin
--sysconfdir=/etc --localstatedir=/var/run --mandir=/usr/share/man
--disable-debug --disable-ipv6 --enable-crypt --with-threads --enable-slurpd

but it's the same.

Thank you in advance.
