Revision history:
0.00 1999, June 1 Petr Vandrovec <vandrove@vc.cvut.cz>
Initial release
0.05 1999, September 5 Philip R. Wilson <prw@home.com>
Added DCK_CONFIDENCE flag.
1.00 1999, November 20 Petr Vandrovec <vandrove@vc.cvut.cz>
Added copyright, couple of important functions and so on...
1.01 1999, November 20 Petr Vandrovec <vandrove@vc.cvut.cz>
Moved wide character functions to wcs.c.
Moved DN handling functions to rdn.c.
1.02 1999, December 14 Petr Vandrovec <vandrove@vc.cvut.cz>
Fixed __NWDSFinishLoginV2, it can return NWE_PASSWORD_EXPIRED on success.
1.03 2000, January 26 Petr Vandrovec <vandrove@vc.cvut.cz>
Added NWDSGetObjectHostServerAddress and NWDSDuplicateContextInt calls.
Fixed NWDSDuplicateContext call to copy DCK_NAME_CONTEXT.
1.04 2000, January 29 Petr Vandrovec <vandrove@vc.cvut.cz>
Fixed NWDXFindConnection to actually work (we always opened
new connection).
1.05 2000, April 26 Petr Vandrovec <vandrove@vc.cvut.cz>
Added NWDSGetCountByClassAndName.
1.06 2000, April 27 Petr Vandrovec <vandrove@vc.cvut.cz>
Added NWDSGetServerName.
1.07 2000, May 6 Petr Vandrovec <vandrove@vc.cvut.cz>
Modified NWDSGetAttrVal and NWDSComputeAttrValSize to
support DSV_READ_CLASS_DEF buffers.
1.08 2000, May 21 Petr Vandrovec <vandrove@vc.cvut.cz>
Fixed NWDSModifyObject iteration handle.
1.09 2000, July 2 Petr Vandrovec <vandrove@vc.cvut.cz>
Modified NWDSGetAttrValModTime to work on buffers returned
from NWDSReadAttrDef.
1.10 2000, July 6 Petr Vandrovec <vandrove@vc.cvut.cz>
Added handling of alias referral to NWDSResolveName.
1.11 2000, July 8 Petr Vandrovec <vandrove@vc.cvut.cz>
Changed handling of charset conversions (you must add
"alias WCHAR_T// INTERNAL" into /usr/lib/gconv/gconv-modules
for non-hardwired conversions).
Local charset is now retrieved from config file instead of
hardcoded ISO-8859-1.
libc5/6 compatibility iconv now handles also UTF-8.
1.12 2000, August 25 Petr Vandrovec <vandrove@vc.cvut.cz>
Added fallback code to NWDSResolveName. Now we try
other attached servers, and if everything fails,
we try resolve name with walk tree on all servers.
It can slow down resolve process when there are
dead servers.
Removed DS_RESOLVE_WALK_TREE from all requests. Resolving
code add this yourself when needed...
1.13 2000, August 27 Petr Vandrovec <vandrove@vc.cvut.cz>
Added "UCS-4LE" and "UCS-4BE" to list of known wchar_t
encodings. But as glibc2.2 knows "WCHAR_T" encoding,
everything should be happy on glibc2.2 systems.
1.14 2001, January 5 PP
Added NWDSWhoAmI, NWDSScanForAvailableTrees....
1.15 2001, January 16 PP
Added Syntaxs API's ( #include ds/syntaxe.c)
1.16 2001, March 7 Petr Vandrovec <vandrove@vc.cvut.cz>
Fixed NWDSScanConnsForTrees to match NWSDK doc.
1.17 2001, March 10 Petr Vandrovec <vandrove@vc.cvut.cz>
Added default tree name and default name context retrieval.
1.18 2001, May 31 Petr Vandrovec <vandrove@vc.cvut.cz>
Use size_t/nuint32 types as needed.
1.19 2001, June 3 Ben Harris <bjh21@cam.ac.uk>
Fix connection leak when NWDSResolveName dereferences alias.
1.20 2001, November 11 Hans Grobler <grobh@sun.ac.za>
Fix SYN_BOOLEAN NDS encoding.
1.21 2001, December 31 Petr Vandrovec <vandrove@vc.cvut.cz>
Added NWDSDuplicateContext. It is obsolete in NWSDK, but handy
for Perl...
1.22 2002, January 1 Petr Vandrovec <vandrove@vc.cvut.cz>
Now you can call NWDSFreeContext with NULL context handle.
1.23 2002, February 3 Petr Vandrovec <vandrove@vc.cvut.cz>
Limit length of string returned by NWDSGetAttrName by
MAX_SCHEMA_NAME_BYTES.
