Hi all,
Im trying to access our SAP ABAP system via our webdispatcher.
The redirect works, as Im getting the logon screen from our SAP abap system that I want to login to.
However, when I fill in my userID and password, nothing happens. The login screen appears again.
Our Webdispatcher doesnt have a DNS name(yet) so I am accessing it via IP :
http://<ip webdispather>:8101
As Im getting the logon screen of our ABAP system, I can assume that the redirect is working fine, and all profile parameters are correct in the webdispatcher.
The only thing I can think of, but cannot test yet, is that the webdispatcher needs to have a DNS name to able to get this working ?
Does anyone have any suggestions ?
Thanks in advance,
Menno
Hi Meeno,
It is a good practise to use FQDN in webdispatcher and other SAP url.
Secondly check in SMICM whether http port is active
Also check in SICF whether relevant services are active.
You may perform manual checks with testing the webgui ITS service using saplogon pad.

Hi Deepak,
webdispatcher URL :
When you enter this you will see the redirect works.
Hi Deepak,
Thank you for your reply,
That won't work for Obvious reasons:
The webdispatcher URL is only available with the port I defined when installing the webdispacther, (and shown in the instance profile of the webdispatcher with parameter )
From there it will redirect to the ABAP system ms port, and from there it will connect to the ICM of the SAP system.
When I am on the SAP server, and test the SICF service, it goes Ok.
This tells me that the SICF service is working fine.
Also, when I test the /sap/bc/.../webgui URL from the webdispatcher, I get the same result:
logon screen --> enter userID and password --> nothing happens

Hello,
I think the problem is indeed the use of an ip adress instead of a FQDN. When you logon successfully, you are supposed to get a MYSAPSSO2 cookie and to resend it for each successive URL.
A web browser sends only a cookie to all the servers part of the domain of the cookie.
As you don't use a domain no cookie is sent and you are not athenticated.
You should be able to verify this using an httpwatch trace.

Hi All,
Indeed the issue is caused by using ipaddress instead of FQDN.
I added the ABAP system in the hostfile of the webdispacther, and added the webdispatcher server in the hostfile of the ABAP server.
I added both systems in my own hostfile on my laptop.
Also I added the fqdn in the instance profile of the webdispatcher, instead of the ipadress.
Thank you all for pointing me in the right direction.
Best regards,
Menno

Hi all,
I have asked for a DNS name for our webdispatcher.
As soon as this is available I will let you know the results.
@Joshua: I can telnet from ABAP to Webdispatcher and vise versa on the ports that are defined, so no port issue.

What happens when you try to login to the abap server (http) and not via the webdispatcher ?

If i understand correct you installed the webdispatcher on a server and you try to redirect communication to a different ABAP server.
In order to investigate I would start by installing the web dispatcher locally on the ABAP server first.
Use the minimal .pfl file you can
Here is an example of a simple and working pfl (using 8080 as the webdispatcher port)
Try to login to the webdispatcher admin console:
http://<server>:<webdips_port>/sap/wdisp/admin/default.html
Make sure the status is green and running.
After that do the following:
1. Open a new browser session. If you use Internet Explorer go to file >> new session
2. try to login to the webgui using server name but this time use the webdispacther port:
http://<server>:<webdisp_port>/sap/bc/gui/sap/its/webgui
Update on the results (if you wish try this).
Hi,
Please share the screenshot for same.
Thanks,

Hi ,
Please check you've activated webgui in transaction code SICF under bc -> gui
Also your access link would be like http://<your IP or FDQN Name>:8001/sap/bc/gui/sap/its/webgui.
As suggested by Deepak good to maintain FDQN for SAP urls.
Thanks,
Gaurav
Hi Gaurav,
In sicf everything is activated: I can do a test of this service,and I get the same logon screen,only from within sicf, I can actually logon.
I will try to get DNS name and FQDN up and running asap, but to my understanding for testing purposes, IP address should also work.
I just cant figure out why this is happening....
