Subject: [PATCH 78/78] Ticket #447 - Possible to add invalid attribute to
cc3dff
 nsslapd-allowed-to-delete-attrs
cc3dff
cc3dff
Bug description: If given value of nsslapd-allowed-to-delete-attrs are
cc3dff
all invalid attributes, e.g.,
cc3dff
  nsslapd-allowed-to-delete-attrs: invalid0 invalid1
cc3dff
they were logged as invalid, but accidentally set to nsslapd-allowed-
cc3dff
to-delete-attrs.
cc3dff
cc3dff
Fix description: This patch checks the validation result and if there
cc3dff
is no valid attributes given to nsslapd-allowed-to-delete-attrs, it
cc3dff
issues a message in the error log:
cc3dff
  nsslapd-allowed-to-delete-attrs: Given attributes are all invalid.
cc3dff
  No effects.
cc3dff
and it returns an error.  The modify operation fails with "DSA is
cc3dff
unwilling to perform".
