CertRequest with empty certificate_autorities list received


In SM59 I've configured a HTTPS connection to a web service with a client certifiate authentication.

These are some key facts:

- I created Individual SSL Client PSE

- I imported the certifiate using sapgenpse import_p12 and then the generated PSE imported into STRUST.

- All root/intermediate CA certificates are stored in CA database.

- WS certificate is listed on Certificate list in STRUST

- ICM service restarted

I tested the certificate using openssl s_client and just with a browser.

This is truncated output of s_client command which shows that the SSL handshake has been completed:

SSL handshake has read 3902 bytes and written 4356 bytes


New, TLSv1/SSLv3, Cipher is RC4-SHA

Server public key is 2048 bit

Secure Renegotiation IS supported

Compression: NONE

Expansion: NONE

.. but when I run connection test in SM59 I get this (dev_icm):

I can't seem to find any information on scn or in any sap note. Let me know if you need any additional details.

    Ok case closed. The problem turned out to be on the WS side. The WS administrator added the Issuer CA to the list of Certification Authorities whose clients the WS deals with.
