domainComponents (DC)).

ldo_rebindproc value has a sane value.

except where we should.

implement an at_exit() handler.

support for DCE slash-delimited, left-to-right DNs;
support for a domain socket transport (enable with
--enable-ldapi); and extensions to URL parsing to
support the latter transport.

Used only for simple bind when dn == NULL and password != NULL.

Changes for URI spport:  New routines ldap_initialize and ldap_create; LDAPURLDesc replaces LDAPServer, LDAPURLDesc list used instead of ldo_defhost.

ldap_pvt_tls_config() was missing first param.

Replace old Id as needed (back-tcl).
Leave updating of contribWare to contributors (for now).

Use ldap_int_tblsize instead of s+1 in select.
Need to eliminate all to read(2).

Needs a bit more work.
	- global net/api timeouts are not inherited on session creation.
	- need configure check for inet_aton() (coming soon)
	- ioctl/fcntl portability issues (should share implementation
		with lber routines)

	ldap_defaults.h incorporates non-generated ldapconfig.h values.
	ldap_config.h.in is new template for autoconf generated defaults
		(namely directories and paths)
	ldap_config.h.nt, NT template (must be manually copied)
	s/<ldapconfig.h>/<ldap_defaults.h>/
	s/DIRSEP/LDAP_DIRSEP/ & s/DEFAULT_/LDAP_/

and ripple change through -lldap.

library use:
  LBER_ macros expand to system routines.
  LDAP_ macros expand to new ber_ allocators.

Add ber_ and ldap_ memory allocators/deallocator:
  ber_ routines are wrappers of LBER_ macros.
  ldap_ routines are wrappers of ber_ routines.

Removed safe_realloc() macro from various files.  This issue
(if an issue) should be resolved across whole package.

ldapmodify.c now uses ber_ allocators to resolve ber_bvfree()
vs. WIN32 multiple heaps issue.

These changes should facilate implementation of
  ber_set_option( NULL, LBER_OPT_MEMORY_FN, ...)
and
  ldap_set_option( NULL, LDAP_OPT_MEMORY_FN, ...).

Added validation to exposed opaque data structures (BerElement, Sockbuf,
and LDAP).  Added macros BER_VALID, SOCKBUF_VALID, LDAP_VALID.
Added ber_pvt_ber_bytes() and ber_pvt_ber_remaining() macros to hide
some ber internals.  These really should be handled by ber_get_option().

prototype in ldap-int.h.

 added comments
 removed LDAP_MAX_ATTR_LEN
 removed LDAP_COMPAT* from <ldap.h> but not code.
 move LDAP_DEFAULT_REFHOPCOUNT to ldap-int.h
 added experimental options macros
 added LDAP_CONTROL_REFERRALS macros
libldap:
 Replace ld_attrbuffer with per use allocated attributed.
 ldap_first/next_attribute attributes now must be freed (as per draft).
 unifdef -DLDAP_API_FEATURE_X_OPENLDAP_V2_REFERRALS

to avoid unportable casts of integers to pointers and back.

These functions require their arguments to be in the range of `unsigned char'.

Redefine Debug macro to call ldap_log_printf(NULL, lvl, fmt, ...)
Should replace each Debug statement with direct call to ldap_log_printf
passing LDAP session if available.

Updates regarding threads and names.

environment settings.

Updated other codes as needed.
