LL_SessionAllocFromCookieEx Function in VB

ELPASOUser3_(Delete)_2549572

I am trying to use the LL_SessionAllocFromCookieEx. We have NTFS authentication set up for logging in and I am able to login to LiveLink with my system user ID and password without a login prompt. I am able to retrieve the "LLCookie" cookie back and pass it to the function. I am appending the "/" to the beginning of the cookie and the ";" to the end of the cookie as noted in the instructions. I just cannot seem to be able to figure out the correct config parameters to pass to the function to be able to login to LiveLink with this function. I receive the message that the server returned an invalid response. Status Code is: -2147418069Any help is greatly appreciated!! I have not been able to find any sample code and I am a little confused by the documentation as to what I need.This is an extract of the code I am using: If (status = LL_OK) Then status = LL_ValueAlloc(config) Else testLogin = "Failed" Exit Function End If If (status = LL_OK) Then status = LL_ValueSetAssoc(config) Else testLogin = "Failed" Exit Function End If If (status = LL_OK) Then status = LL_AssocSetInteger(config, "HTTPS", LL_FALSE) Else testLogin = "Failed" Exit Function End If If (status = LL_OK) Then status = LL_AssocSetString(config, "LivelinkCGI", "http://" & serverName & "/livelink/livelink.exe") Else testLogin = "Failed" Exit Function End If If (status = LL_OK) Then 'status = LL_AssocSetString(config, "HTTPUserName", "myHTTPUserName") Else testLogin = "Failed" Exit Function End If If (status = LL_OK) Then 'status = LL_AssocSetString(config, "HTTPPassword", "myHTTPPassword") Else testLogin = "Failed" Exit Function End If server = serverName port = 2099 status = LL_SessionAllocFromCookieEx(session, server, port, cookieValue, config)

When tunneling through a web server instead of directly accessing the Livelink Server, the port parameter is the web server's port (default 80 or 443 for HTTPS). The server is returning an invalid response because you're not connecting to the web server.

I can use port 80 when using a web page on the machine that has IIS installed on it. When I try and run the same page from a remote machine I receive the following error code. Anyone with any ideas why it would work on one machine and not another? I have tried using the IP address and the internal server name both with the same results.

We are just using a standard IIS install with no customization at all. Like I say this works if I use a web page on the host machine where LiveLink and IIS are installed. It logs in every time. When I try to login from a different machine I get the error. I am able to login to livelink from the client machine using the NTFS authentication.Thanks,Bill Mendesbmendes@col-col.com

Bill,

You can connect from the client machine through a web browser, correct? Verify the servername is the same. Also, try putting the port into your LivelinkCGI parameter (http://servername:80/livelink/livelink.exe).

Bill,

What Directory Security do you have setup in IIS for the Livelink virtual directory? It's a problem if you only have Integrated and nothing else because your LAPI application doesn't support CHAP (Challenge Handshake Authenticate Protocol). Although I believe you should get a different error in that case.

If you have Basic Authentication selected and not Anonymous, you'll probably have to send a username and password in the HTTPUserName and HTTPPassword so the web server will let you through.

I am using strictly Integrated Windows Authentication. So you are saying that we may have to pass the user's password to the program in order to login?If I checkoff (enable) Anonymous Access then the login to Livelink becomes required. Sounds like I am caught between that rock and a hard place??Thanks,Bill Mendesbmendes@col-col.com

Bill,

Fortunately, there's something called Basic Authentication between that rock and a hard place. Integrated Authentication will only work for applications like Internet Explorer. Even Netscape does not use it. So, since LAPI can't use Integrated and you can't have Anonymous enabled with Directory Services, you must turn on Basic Authentication (and leave Integrated enabled as well).

Anonymous access requires no credentials be sent from the client. Integrated and Basic require the user logs into the web server (however, with Integrated it's usually seamless because IE sends your network token). In Basic you must send a username and password the web server recognizes before it will let you through to Livelink. These are specified in the HTTPUserName and HTTPPassword parameters of the config assoc. The web server will recognize any user in the domain the server is in by default.

Note that the username should be given as "domain\username".

Kevin

Hi Kevin:First thanks for all your help in this. I do understand the authentication in IIS. I just could not remember how many ways I had attempted it in the past week !!I have both Basic and Integrated checked on the web server in IIS. I am passing the following in the config parameterstatus = LL_AssocSetString(config, "HTTPUserName", "GW285\Administrator")status = LL_AssocSetString(config, "HTTPPassword", "password")The user name and password are the Administrator's id and password on the server. I used them just to eliminate any other questions about rights, etc on the remote machine (server).It still only allows me to login to the server. When I am getting the Basic Authentication Box to login, I have tried the administrator on the machine, I have tried a valid User on our system and both fail. Again it works flawlessly when I log in directly via the server. I still get the Status of -2147482645 returned. I can't find that code documented so I am not even sure what the error is....Thanks,Bill Mendesbmendes@col-col.com

Bill,

If you're logging in as a local user to the server the username should be only "Administrator". You should only pass the doman if the user is a domain user.

We seem to have found the answer to this long thread.We needed to add the config parameter of:"EnableNTLM", LL_TRUE and it seems to be working just fine now with a standard login vs. using the cookie. If (status = LL_OK) Then status = LL_ValueSetAssoc(config) Else getLoginSession = "Failed" Exit Function End If If (status = LL_OK) Then status = LL_AssocSetInteger(config, "HTTPS", LL_FALSE) Else getLoginSession = "Failed" Exit Function End If If (status = LL_OK) Then status = LL_AssocSetString(config, "LivelinkCGI", "/" & gStrLiveLinkVirtualDir & "/livelink.exe") Else getLoginSession = "Failed" Exit Function End If If (status = LL_OK) Then status = LL_AssocSetString(config, "HTTPUserName", gStrHTTPUserNAme) status = LL_AssocSetString(config, "HTTPPassword", gStrHTTPPassword) status = LL_AssocSetInteger(config, "EnableNTLM", LL_TRUE) Else getLoginSession = "Failed" Exit Function End If port = 80 If (status = LL_OK) Then status = LL_SessionAllocEx(gLngSession, gStrServerLocation, port, "", "", "", config) Else getLoginSession = "Failed" Exit Function End If

Hi,I have the same problem with the LL_SessionAllocFromCookieEx function. The function works okay when the user is on the server system. When the user comes from a different system an error is the result.I see in your solution that you stopped using the cookie. But that requires the user to login to livelink. The idea of using the cookie is that the current livelink session of the user can be used. Did you find any way of avoiding the 'double' login without using the cookie.Kind regards,Adrie
