Hi,
I've been looking into nss_ldap myself over the past few days and I read something related to this just yesterday.
I include the important part of the text and a link to the page where I found it.

Important: Systems that use bash as their /bin/sh may have problems while
umounting or shutting down if NSS lookups go over LDAP. This is because the shell
script /etc/init.d/umountfs (may also be found under /etc/rc.d/init.d/umountfs)
which umounts all filesystems during shutdown is executed by bash which in turn
calls getpwnam(3), loading LDAP shared libraries. This can result in the
filesystem where the LDAP shared libraries reside not being able to umount
because it is busy with the mmapped shared libraries. 

A possible workaround is to change the shebang-path in /etc/init.d/rc and
/etc/init.d/umountfs from /bin/sh to /bin/ash (as well as all calls to sh in
these scripts). Ash doesn't have the getpwnam(3) problem.

This very much seems like what you are experiencing on your machine.
I hope this can help you.
