Hi,

got repeatable slapd server crash when I try to remove the ENTIRE
ATTRIBUTE CONTENTS of INDEXED ATTRIBUTE.

According to ldap_modify man page

       ... If the entire attribute is to be deleted, the
       mod_values   field   should   be   set   to   NULL...

I was trying to remove all the indexed uid attribute. Got Segmentation 
fault in slapd. The reason is in vals=0x0.
