It would be unusual, but not impossible for "getent shadow ..." to have 
the password hashes available.  If that is the case, you have a 
relatively poorly secured LDAP server.

On the other hand, it's fairly common for "getent shadow ..." to show 
you the shadow information other than the password hashes.

In neither case will nscd allow you to log in to the machine when the 
network is down.  nscd is the wrong tool for this.

I didn't meant to imply that the LDAP server wouldn't supply anything at 
all, just that most of them won't hand out password hashes.

Did you build it from source or were you trying to install one of the 
binary packages?  You'll definitely want to build from source.
