[Bug 644632] Re: nssldap-update-ignoreusers needs to be configurable to ignore users

[Jamie Strandboge]

Based on the above test case, NAK on the current patch. It has a
trailing ')' in the OKUSERS line, does not output the correct
'nss_initgroups_ignoreusers' line (ie, uucp and www-data are still
listed) and the man page has not been updated.

  Currently, nssldap-update-ignoreusers can only be configured to ignore
  users over a certain numeric UID.  It blindly includes all users less
  than the configured UID.  However, this breaks our setup.  We have
  some system users (namely www-data and www-priv) that are in groups in
  LDAP.  Thus, when you query the 'Subversion' group, you get back a
  list that includes www-priv.  However, if you try to query the groups
  to which www-priv belongs, it fails to return the correct groups
  because it ignores www-priv, thus breaking privileges because the
  system then thinks www-priv is not in the Subversion group.

  The only work around for now is to disable the run of nssldap-update-
  ignoreusers.

  I would work on a patch to facilitate configuring users to *not*
  include in the ignore list if someone will commit to getting the patch
  accepted: we don't really want to maintain our own branch of one file
  in a package. :)
