[TwixEncoder] :: delivers different PDUs for same search result on
different operating systems
Hi List-Members,
the following mail was first sent to users@directory.apache.org but I
think this is more a developer issue. Maybe someone can throw an eye on
it maybe help me out to find a solution?
TIA
Markus

Hi list-users,
I do have problem with my content management system working with
apacheds on a windows 2003 server installation.
My content management system (coremmedia 2005) tries to identify each
user by ldap request against apacheds 1.5.x ldap server.
What I found out is, that the ldap request against an apacheds-1.5.x on
a windows 2003 server system isnt successful, while the same request
against a centos 4.3 or fedora 7 apacheds-1.5.x installation is successful.
How did I find that out? Well, I configured my CMS to connect against
apacheds-1.5.x on a windows 2003 server, where apacheds logs are in
debug mode. Then I tried to load CMS startpage, which is not successful.
Then I did the same with CMS connected against apacheds-1.5.x running on
centos 4.3 with logfiles in debug mode. Now the startpage was loaded.
I then searched thru the logfiles and found out the following:
- the search request from CMS is always the following:
[19:48:34] DEBUG [org.apache.directory.shared.ldap.codec.TwixDecoder] -

But the next line in debug log which contains the Encoded PDU differs
from windows 2003 server to centos43.
The windows 2003 encoded PDU looks like this:

Putting this two PDU strings in a small program that converts that hex
strings to readable char string delivers the following:
Windows 2003 Server:
0°dª5uid=Jeder, cn=users, dc=VERWALTUNG,
dc=DOUGLASHOLDING0q0
sn1Jeder0A objectClass12personorganizationalPerson
inetOrgPersontop0 cn1Jeder0uid1Jeder
CentOs 4.3:
0d§2uid=Jeder,cn=users,dc=VERWALTUNG,dc=DOUGLASHOLDING0q0uid1Jeder0
sn1Jeder0
cn1Jeder0A objectClass12organizationalPersonperson
inetOrgPersontop
My question is: what makes the difference? Where is the mistake? Where
is my mistake? What can I do? Is it a bug?
Any tips and hints are really appreciated. If neccessary, I can send
server.xml and logfiles from both servers, or whatever is needed.
Thanks in advance,
Markus
