After trying to "configure --without-threads ...", the build resulted in the
following error message:
connection.o: In function
`connection_operation':/home/owen/rk/nim/openldap/openldap-cvs/servers/slapd/connection.c:1044:
undefined reference to `ldap_pvt_thread_pool_tid'
connection.o: In function
`connection_fake_init':/home/owen/rk/nim/openldap/openldap-cvs/servers/slapd/connection.c:1955:
undefined reference to `ldap_pvt_thread_pool_tid' 

This can be resolved by creating the trivial do-nothing
ldap_pvt_thread_pool_tid() function in thr_stub.c

Here is the trivial patch rkowen-061026.patch
