NAME
     ldap_get_dn, ldap_explode_dn,  ldap_dn2ufn,  ldap_is_dns_dn,
     ldap_explode_dns,  ldap_dns_to_dn  -  LDAP DN handling func-
     tions

     char *ldap_get_dn(LDAP *ld, LDAPMessage *entry);

DESCRIPTION
     These functions allow LDAP entry names (Distinguished Names,
     or DNs) to be obtained, parsed, converted to a user-friendly
     form, and tested. A DN has the form described in RFC 1779  A
     String  Representation  of Distinguished Names, unless it is
     an experimental DNS-style DN which takes the form of an  RFC
     822 mail address.


     The ldap_get_dn() function takes an  entry  as  returned  by
     ldap_first_entry(3LDAP)    or   ldap_next_entry(3LDAP)   and
     returns a copy of the entry's DN.  Space  for  the  DN  will
     have  been  obtained  by  means of malloc(3C), and should be
     freed by the caller by a call to free(3C).


     The ldap_explode_dn() function takes a  DN  as  returned  by
     ldap_get_dn()  and  breaks  it  up into its component parts.
     Each part is known as a Relative Distinguished Name, or RDN.
     ldap_explode_dn() returns a null-terminated array, each com-
     ponent of which contains an RDN from the  DN.   The  notypes
     parameter  is  used  to  request that only the RDN values be
     returned, not their types.  For  example,  the  DN  "cn=Bob,
     c=US" would return as either { "cn=Bob", "c=US", NULL } or {

     "Bob", "US", NULL }, depending on whether notypes was  0  or
     1,   respectively.  The  result  can  be  freed  by  calling
     ldap_value_free(3LDAP).


     ldap_dn2ufn()  is  used  to  turn  a  DN  as   returned   by
     ldap_get_dn()  into a more user-friendly form, stripping off
     type names.  See RFC 1781 "Using the  Directory  to  Achieve
     User  Friendly  Naming"  for more details on the UFN format.
     The space for the UFN returned is  obtained  by  a  call  to
     malloc(3C),  and  the  user is responsible for freeing it by
     means of a call to free(3C).


     ldap_is_dns_dn() returns non-zero if the  dn  string  is  an
     experimental  DNS-style  DN (generally in the form of an RFC
     822 e-mail address).  It returns zero if the dn  appears  to
     be an RFC 1779 format DN.


     ldap_explode_dns() takes a DNS-style DN  and  breaks  it  up
     into  its  component  parts.  ldap_explode_dns()  returns  a
     null-terminated array. For example, the  DN  "mcs.umich.edu"
     will return { "mcs", "umich", "edu", NULL }.  The result can
     be freed by calling ldap_value_free(3LDAP).


     ldap_dns_to_dn() converts a DNS domain name  into  an  X.500
     distinguished  name.  A  string  distinguished  name and the
     number of nameparts is returned.

ERRORS
     If an error occurs in ldap_get_dn(), NULL  is  returned  and
     the  ld_errno  field  in the ld parameter is set to indicate
     the error.  See ldap_error(3LDAP) for a description of  pos-
     sible error codes. ldap_explode_dn(), ldap_explode_dns() and
     ldap_dn2ufn() will return  NULL with errno(3C) set appropri-
     ately in case of trouble.


     If an error  in  ldap_dns_to_dn()  is  encountered  zero  is
     returned.  The  caller should free the returned string if it
     is non-zero.
