The ldap_first_attribute() and ldap_next_attribute() routines are
used to step through the attributes in an LDAP entry.
ldap_first_attribute() takes an entry as returned by
ldap_first_entry(3) or ldap_next_entry(3) and returns a pointer to
character string containing the first attribute description in the
entry. ldap_next_attribute() returns the next attribute description
in the entry.
It also returns, in berptr, a pointer to a BerElement it has
allocated to keep track of its current position. This pointer should
be passed to subsequent calls to ldap_next_attribute() and is used to
effectively step through the entry's attributes. The caller is
solely responsible for freeing the BerElement pointed to by berptr
when it is no longer needed by calling ber_free(3). When calling
ber_free(3) in this instance, be sure the second argument is 0.
The attribute names returned are suitable for inclusion in a call to
ldap_get_values(3) to retrieve the attribute's values.
