if there is no OTDS integration involved this code sample may help you.The basic premise is insted of openeing a session against the lapi port you want to tunnel into the application authenticating yourself at the webserver.It will do you good if you can establish SSO works within the livelink gui andusing the lapi test connection utility.That helped me greatly when I wanted to do something like this.

Sorry the WIKI where all the lapi samples were stored is broken

Here's a direct link to the code in my PWS

LAPI is old technology which is not supposed to be used with newer livelink so I am assuming you want to use it.If it is Enterprsie Web Services I have posted a SSO example here as well www.livelink.in although no real testing other than me has done it.

I have attached example code I provide to fellow Java developers that shows how to use both standard and directory service authentication.

In order to compile this example, you obviously need the LAPI.jar file and you need to update the example host, port, cgi, username and password values. To run this example, you will need the llkernel.dll and lapi_base.dll for the Directory Service based authentication or you will get a "The webserver requires an unsupported authentication method" error when using Directory Service authentication.

Thank You For Your Example . When I Run The LLSessionUtilities Class , RunTimeException Was Throw . The Exception Message is :

2003 - Admin Home

Directory Service Example Failed!

LAPI Error! (-2147482645)

How Can I Fix The Bug . Thank You .

I Have Some Question .

1. llkernel.dll and lapi_base.dll . Where Should I Stored The DLL? (Now I Stored The DLL Path :C:\CS10\cgi)?

2.Should I Use The CreateDomain API OR AddDomainToGroup API Before Run You LLSessionUtilities Class?

3.Should I Config The Livelink Administrator Server Before Run You LLSessionUtilities Class?

Here is a OT tool to see if your livelink can understand NTLM(AD,SSO)

https://knowledge.opentext.com/knowledge/cs.dll?func=ll&objId=3501512&objAction=ArticleView

If the call with the utility works then it is almost certain that you can use your own code to do it following Ossie's or my code excerpt.

If you are completely new to LAPI then here are some things you need to do

Read on how to set up a client project whether you are programming in java or a .net language.The install files for lapi won't probably work in 64 bit but you could copy them from a 32 bit env.If you are doing .NET then the project in VSS ide should be made into .NET 2 framework version.If you are doing this in 32 bit lapi installer will amend your PATH for you.
I just browse the files that OT made up client lapi files into my project see the word arttachment as in this link https://knowledge.opentext.com/knowledge/cs.dll?func=ll&objId=31612923&objAction=download&viewType=1
You should really try to do a simple example in lapi rather than the AD stuff right on.

If you are not a sysadmin of livelink,find him /her and execute this command from the browser

your livelink url ending in livelink.exe or llisapi.dll or livelink ?func=admin.testargs

look if REMOTE_USER is populated with domainname\username if it is not then this instance of livelink does not understand NTLM

See how far you get this time

The DLLs do actually come into play for LAPI when tunneling the connection to a Directory Service authentication. I'll post a complete reply tonight, but if you use the tunneled connections to a Directory Services enabled URL you will need to have the noted DLLs on your path even with Java. You can do this by adding the full path to the DLLs to your Windows PATH variable.

When I installed the LAPI SDK, the llkernel.dll and lapi_base.dll files were installed to "C:\Program Files\Open Text\LAPI\bin\". I added "C:\Program Files\Open Text\LAPI\bin" to my PATH variable by doing the following:

1. Right click on My Computer, select Properties

2. Click on the Advanced tab.

3. Click Environment Variables

4. Located the PATH variable in the System variables section.

5. Select the PATH variable and click Edit

6. To the end of the existing PATH variable value, append ";C:\Program Files\Open Text\LAPI\bin" (the ';' character delimits the values) This resulted in my PATH variable of... "C:\Program Files\ATI Stream\bin\x86;C:\Common\Oracle\OraHome\BIN\;%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;C:\Program Files\Intel\WiFi\bin\;C:\Program Files\ATI Technologies\ATI.ACE\Core-Static;C:\Program Files\Open Text\Livelink Explorer\;C:\Program Files\Java\jdk1.7.0_03\bin;C:\Program Files\Windows Imaging\;C:\winnt\system32\WindowsPowerShell\v1.0;C:\Program Files\RSA Security\RSA SecurID Software Token\;C:\Program Files\Open Text\LAPI\bin".

7. Save and exit the System Properties dialog.

8. Confirm your PATH variable now includes the LAPI bin directory by opening a DOS windows and typing: echo %PATH%

Close and re-open your IDE (or application, or DOS window, or whatever you are running the example using). The AD authentication should now work.

It is important to note that because you do not (typically) provide username and password information for AD authenticated, tunneled LAPI requests, you are connecting as the user running the application. That user must obviously be able to login to Livelink normally.

As I said, I'll post a link to a complete example later tonight so that you can actually see step by step how to use the LAPI DLLs to allow your Java application to connect to a Directory Service enabled Livelink URL.

it looks like you programmed in Java using Ossies but quoted me on my C# stuff.In any case if you were using java then the dll's don't come into play.The lapi.jar files should be in the path I beleive or classpath.If Ossie won't help I can check that for you.

Thank You For Your Help . I Have Been Set The Windows Environment . But The Java Was Throw The Exception . The Exception Is :

Directory Service Example Failed!

LAPI Error! (-2147482645)

Status Code: -2147482645

Api Error:

Error Message:

Status Message:

So I Want To Ask You ? Are You Install anything Module To Livelink For Use Active Directory Authentication?

Are You config Anything For The Lievlink Administrator?

Thank You Very Much .

Ossie_Moore

The specifics of setting up and configuring Directory Service authentication such that users are authenticated via Active Directory varies depending on the version of IIS and Livelink and is beyond the scope of a forum reply for allowing LAPI to connect. However, here is an 50000 foot view of what you do:

1. You must install and configure the Directory Services module.

2. IIS must be configured to authenticate the user via Windows Authentication on the servers that the end users will make their requests to. (Note that you should probably also setup a standard authentication URL so that Admin can access these servers easily.)

Once users can connect to Livelink on these front end servers successfully using Active Directory authentication, you can then tunnel your LAPI requests through these front end servers to also use Active Directory authentication.

As I promised earlier, here is a complete example from scratch using nothing but notepad, the JDK and LAPI to connect to Livelink using an Active Directory URL. The video has a link to the resulting Java source for your convenience. http://vimeo.com/56452096

Dear Ossie,

I Had Been Install Directory Services Administrator module.I Had Been Configure the external directory sources to be used for synchronization.,I Had Been Check The IIS configured to authenticate the user via Windows Authentication on the servers. But I Get The Sample Exception.

Directory Service Example Failed!

LAPI Error! (-2147482645)

So I Have Some Question .

1.configure the Directory Services Administrtaor module,I Had Been ynchronization The AD user To Livelink User And I Had Been Config The Configure Authentication Source.Can You Tell Me What Should I Config?

2.Note that you should probably also setup a standard authentication URL so that Admin can access these servers easily

what mean?

3.Livelink Version is 10.Can I AD Login . Thanks

Thanks A Lot
