Resolves: bug 440474
Bug Description: A number of memory leaks in the memberOf plug-in occur 
during
  various operations on member attributes.  These leaks were discovered 
using
  valgrind to run ns-slapd.

Fix Description: We were allocating a Slapi_Mods in the modify callback 
and never
  calling slapi_mods_free() would cause a double free. This is because 
we are
  initialing the Slapi_Mods by passing in the LDAPMod array from 
SLAPI_MODIFY_MODS
  in the pblock.  This will make slapi_mods_free() do a free of the 
LDAPMod elements,
  but do_modify() is responsible for freeing the LDAPMod array in the 
pblock.  The
  solution is to initialize the Slapi_Mods by reference so 
slapi_mods_free() doesn't
  try to free the LDAPMod array.

  There were 4 places where we were allocating a Slapi_Entry by calling
  slapi_search_internal_get_entry(), but never freeing the entry when we 
were
  finished with it.

  We were allocating two Slapi_Value arrays with slapi_ch_malloc(), but were
  never calling slapi_ch_free() when we were finished.
Platforms tested: RHEL5.1 x86_64
Flag Day: No.
Doc impact: None.
