DESCRIPTION
       These  routines  are  used  to perform LDAP user friendly search opera-
       tions.  ldap_ufn_search_s() is the simplest form.  It does  the  search
       synchronously.   It  takes ld to identify the the LDAP connection.  The
       ufn parameter is the user friendly  name  for  which  to  search.   The
       attrs, attrsonly and res parameters are the same as for ldap_search(3).

       The    ldap_ufn_search_c()    routine    functions    the    same    as
       ldap_ufn_search_s(),  except  that  it  takes cancelproc, a function to
       call periodicly during the search.  It should be a  function  taking  a
       single  void  * argument, given by calcelparm.  If cancelproc returns a
       non-zero result, the search will be abandoned and no results  returned.
       The  purpose  of  this routine is to provide a way for the search to be
       cancelled, for example, by a  user  or  because  some  other  condition
       occurs.

       The  ldap_ufn_search_ct()  routine  is like ldap_ufn_search_c(), except
       that  it  takes  three  extra  parameters.   tag1  is  passed  to   the
       ldap_init_getfilter(3)  routine  when  resolving the first component of
       the UFN.  tag2 is used when resolving intermediate components.  tag3 is
       used  when  resolving the last component.  By default, the tags used by
       the other UFN search routines during these three phases of  the  search
       are "ufn first", "ufn intermediate", and "ufn last".

       The  ldap_ufn_setfilter() routine is used to set the ldapfilter.conf(5)
       file for use with the ldap_init_getfilter(3) routine to fname.

       The ldap_ufn_setprefix() routine is used  to  set  the  default  prefix
       (actually,  it's a suffix) appended to UFNs before searhing.  UFNs with
       fewer than three components have  the  prefix  appended  first,  before
       searching.   If that fails, the UFN is tried with progressively shorter
       versions of the prefix, stripping off components.  If the UFN has three
       or more components, it is tried by itself first.  If that fails, a sim-
       ilar process is applied with the prefix appended.

       The ldap_ufn_timeout() routine is used to set  the  timeout  associated
       with  ldap_ufn_search_s() searches.  The timeout parameter should actu-
       ally be a pointer to a struct timeval (this  is  so  ldap_ufn_timeout()
       can be used as a cancelproc in the above routines).

NOTES
       These routines may dynamically allocate memory.  The caller is required
       to free such memory using the supplied deallocation  routines.   Return
       values are contained in <ldap.h>.
