Problem to logon via webbrowser to mySAP e-recruiting

Hi,

I did Google the whole web to find a solution for the following problem. I hope anyone of you can help me:

We installed mySAP e-recruiting 300 with the actual service packs in our SAP-System (SAP ERP Central Component 5.0) using the integrated webserver 6.40.

We did all of the necessary customizing.

The problem is: When I like to login as an external candidate via the url I created with the report RCF_GENERATE_URLS the browser shows me the login screen. After I entered the correct login data the screen is showed again... and so on...

It is possible for the user to login into the system via the SAPGUI. He has the role SAP_RCF_EXTERNAL_CANDIDATE.

This problem occurs also when I tried to login as a internal candidate, administrator...

The System works fine when I call the Candidate Registration (HRRCF_CAND_REG) all is working fine and a user is created in the system, which can create a application and can change his stetting. When I close the browser, the user is logged of.

I already checked all OSS. The profile parameters login/accept_sso2_ticket and login/create_sso2_ticket of the Web Application Server are both set to 1. (according the OSS 595109).

Does anyone has a solution for this problem?

Thank you very much for your help.
