Hi Stefan,

The value of the Basic Constraint extension of this website self-signed certificate is "End Entity" and, more importantly, it is set to Critical. So, technically speaking, this certificate can not be a CA and it can't certify itself. The Nokia implementation seems to be strict compared with others but it can't be blamed for checking the correctness of a certificate. The administrators of this website can solve this issue by creating a new certificate without the Basic Constraint extension. A more clean solution would be to a have the server's certificate issued by a root CA of their own, like in any normal PKI architecture.

Cheers,

Dear Openssl-Users,

i recently came across a problem with the offered ssl-cert on
www.mastersnet.de

It's a self signed cert and all of the nokia cell phones, i get my
hands on refuse to accept this cert when trying to import it
manually in the cert store. It is working without problems for
example with a signed cert from cacert (where the root-CA-cert is
also not in the default cert store) I'm asking for your help hereby,
if some of you could please have a look at this cert and tell me, if
there is something suspicous, leading to the reported problem.

It might be a bug in the nokia cell phones. It's working with iPhone
or windows mobile devices.

Thanks in advance

Stefan
