SSL .csr file not being accepted...Please guide

Hello All,

We have configured our portal server on SSL.

To generate the CSR, I followed all instruction I found on SDN and have got a .csr file.

Wanted to try the SAP Trusted Test Certificates before purchasing one, so I went to site: https://service.sap.com/tcs

Under the Test Certificate, I paste the contents from the generated .csr...starting with -

BEGIN NEW CERTIFICATE REQUEST-- - and ends with -

I select server type as 'Web AS 6.20 & newer' and click on 'Continue'

At this step I get an exception saying "The Distiguished Name (DN) in the request for the Test Server certificate contains invalid characters or an email address "

CN = EP1

Please guide me on this.

Pleae dont send me links on this as I have read almost all of them but they do not answer my query.

Awaiting Reply.

Regads,

Ritu
