[issue14748] spwd.getspall() is returning LDAP (non local) users too

[Dave Malcolm]

Dave Malcolm <dmalcolm at redhat.com> added the comment:

Like passwd and group information, the shadow password entries are pulled through libc's Name Service Switch and modules for it, depending on configuration.

See "man nsswitch.conf".

Hence this is likely to be a configuration difference between the two boxes.  Some notes from one of my Red Hat colleagues:
* Is a module listed in /etc/nsswitch.conf so that it'll be used to look
  up "shadow" information?
* Does the module support looking up shadow information?
  The libnss_ldap.so.2 stub from nss-pam-ldapd does; SSSD (at least
  version 1.8.3) doesn't.
* Are there shadowAccount entries in the directory server?
  An IPA server won't have them, because IPA makes use of the directory
  server's built-in password policy functionality to avoid depending on
  clients to enforce aging policies.
* Is the client performing the lookup authorized to read the shadow data
  from the directory server?
* Does the client perform any additional access control?
  The daemon in nss-pam-ldapd only exposes shadow information to
  processes running as UID 0.
etc

Hope this is helpful
