these are things that you have to work out for yourself.

I tend to allow anonymous bind for most things such as users and groups
and deny access to specific attributes such as
userPasswd/sambaLMPasswd/sambaNTPasswd and any other sensitive passwords
to those who are specifically permitted.

You can also set up rootbinddn and rootpasswd in /root/.ldaprc  # I'm
assuming that nscd runs as root...I tend not to use nscd because it
makes debugging difficult. Any 'user' (like root) can have a file
called .ldaprc in their home directory.

I would find it awkward to set /etc/ldap.conf not to be world readable
and that would make it awkward to put such an important password into
that file.

Of course, you could put in a binddn and bindpw that is significantly
less privileged than rootbinddn.
