SAP PI: "Authentication did not succeed"

[nicola_martella2]

Hi people.
I'm working on a SAP PI 7.30 double stack.

I developed a custom java module working on a communication channel adapter file in receive mode.

The module write a file on the file system and works fine.

The problem is that each time the module runs, in Log Viewer I find following error:

LOGIN.FAILED

User: PIISSPI
IP Address: xxx.xxx.xxx.xxx
Authentication Stack: sap.com/com.sap.aii.af.ms.app*MessagingSystem

5. com.sap.security.core.server.jaas.CreateTicketLoginModule OPTIONAL ok true

Any idea about it?
Thanks a lot for your support

Hello Nicola Martella,

Error what I see is : No logon policy was applied

Can you please check SAP help : Setting a Logon Policy for a Policy Configuration

Hi Yogesh.
Thanks a lot for your response.

Really the error is

4. com.sap.engine.services.security.server.jaas.BasicPasswordLoginModule REQUISITE ok exception true Authentication did not succeed.

I'm sorry for not have highlighted it.

I believe that problem is related to the certificate needs for single sign on between Netweaver engines, perhaps attribute missing referred to filesystem use but I'm not sure for this because the file is correctly created into the directory.

Without my custom java module doesn't have the problem.

Unfortunatelly, I haven't enought skills about certificates and so your help is really welcome.

A great ciao.
Nicola
