Yikes.  All of this is *very* old.  OpenLDAP has been in the 2.3.x
family for years, and Samba 3.0.10 is years old.   And RedHat's OpenLDAP
packages are total crap (search the archives of *any* LDAP related
list).   You can get sensible OpenLDAP 2.3.x packages from
<http://staff.telkomsa.net/packages/rhel5/openldap/i386/> for
RHEL5/CentOS5 built by someone who knows what they are doing.  Don't
deploy a production LDAP server using RedHat's antique and lousy
packages;  if you do, and then need assistance, any post on any OpenLDAP
list is going to be met with an immediate "upgrade your software"

This error is spurious and probably completely unrelated to your
problem.   Try increasing your debug level to 10 so you can see what the
real failure is
